Abstract The baffle type and structure are critical to enhancing the comprehensive thermo-hydraulic behavior of shell-and-tube heat exchangers (STHX). In the study, Solidworks software was used to establish three-dimensional mesh models of STHX equipped with the segmental baffle and the continuous helical baffle, respectively. ANSYS software was adopted to study the effects of the baffle type and the baffle geometric parameters on the thermo-hydraulic characteristic of STHXs using the pressure drop of the shell side, the coefficient of heat transfer and isobaric JFP factor as the evaluation characteristics. For segmental baffles, better thermo-hydraulic performance could be obtained with a baffle spacing of 200 mm and a gap height of 0.4 D. For helical baffles, an optimized thermo-hydraulic performance could be obtained with a baffle pitch of 150 mm. By comparing the comprehensive thermo-hydraulic performances of STHXs equipped with two different baffles, it could be concluded that the isobaric JFP factor of STHX equipped with the helical baffle was 1.18 times that of STHX equipped with the segmental baffle under the different suitable flow rate.

Shell and tube heat exchanger (STHX) is an implement that has tremendous applications in numerous industrial processes and research areas. In this study, the commercial software ANSYS is used for 3-D computational fluid dynamics (CFD) to compare the thermo-hydraulic performance of STHXs with recently developed tri-angular (TRI) baffles, and tri-flower (TF) baffles with conventional segmental (SG) baffles at different flow rates. Simulations have been performed to analyze the heat transfer coefficient, pressure drop, and overall thermo-hydraulic performance among the recently developed TRI-STHX, TF-STHX and conventional SG-STHX. The thermo-hydraulic performance of the numerical model of SG-STHX shows the promising results while validating it with the experimental results, Esso and Kern methods. Then the same study is carried out for comparing the two novel baffles with segmental baffle. The results depict that, novel baffles are much appreciable in increasing heat transfer coefficient. The TF-STHX offers a greater heat transfer coefficient than all others but also offers a higher pressure drop at the same flow rate. Computing the comprehensive performance (hs??p), the TRI-STHX offers a prominent increment in thermo-hydraulic performance compared to others. Moreover by inserting twisted tapes at the tube side, there is noticeable increase in heat transfer coefficient which tends to increase the thermo-hydraulic performance of STHX. By comparing the flow patterns of TRI-STHX and SG-STHX, the novel TRI-STHX shows the reduction in shell-side induced vibrations and hence helped to increase the overall efficiency of the STHX.

In the present decade, research regarding solar thermal air heaters (SAHs) has noticed a continuous progression in thermo-hydraulic performance augmentation approaches. There now exists a wide variety of thermo-hydraulic performance augmentation approaches and researchers have designated various structures. Nevertheless, there seems to be no generalization to any of the approaches employed. The present numerical investigation reports on the thermo-hydraulic characteristics and thermal performance for flow through a varied length (full, medium, half, and short length) dimple solar air heater (SAH) tube. The study highlights recent developments on enhanced tubes to augment heat transfer in SAH. The influence of different length ratio, dimple height ratio (H), and pitch ratio (s) on thermo-hydraulic characteristics have been investigated in the Reynolds number (Re) range from 5000 to 25,000. Air is used as the working fluid. The commercial software ANSYS Fluent is used for simulation. The shear stress transport (SST) model is used as the turbulence model. Thermal energy transport coefficient is increased in the full-length dimple tube (FLDT), compared to the medium-length dimple tube (MLDT), half-length dimple tube (HLDT) and short-length dimple tube (SLDT). Similarly, the pitch ratio (s) has more influence on Nusselt number (Nu) compared to the dimple height ratio (H). The friction factor decreases with an increase in pitch ratio. Nu increases and f decreases with increasing Re for all combinations of H and s. Low s and higher H yields high enhancement of HT and PD. Integration of artificial roughness on the tube increases the values of Nu and f by 5.12 times and 77.23 times for H = 0.07, s = 1.0 at Re value of 5000 and 25,000, respectively, in regard to the plain tube. For all the tested cases, the thermo-hydraulic performances (η) are greater than unity.

In the present study, a commercial finite volume package ANSYS FLUENT 14.5 has been used to determine thermo-hydraulic performance of two different vortex generator (VG) configurations, namely, flow-up and flow-down, located in triangular ducts. A comprehensive literature survey on flow-up and flow-down configurations has shown that there are completely opposite results obtained in terms of performance of the two configurations. In some studies, flow-up configuration showed better performance characteristics over flow-down configuration while in other studies flow-down configuration was found better. This has been motivated the present authors to make a study covering the two VG configurations to find out which one has a better performance over the other one. Therefore flow and thermal fields together with the secondary flow induced by the two VG configurations have been analyzed extensively. The geometry comprised of double row of VGs located on the slant surfaces of equilateral triangular ducts. The angle of inclination of the VGs made with the flow direction is 30°. The results show that flow-down configuration has a 40.65% higher thermo-hydraulic performance over the flow-up configuration for Re=5000. It is also shown that the heat is transferred at a further downstream distance allowing in a reduction in the number of VGs to be used in of flow down case.

To improve the heat transfer performance of laminar tubular flow, a center-cleared twisted tape of alternate axes was developed as inserts. Numerical simulation was conducted to investigate the effect of dislocation angle of twisted tapes on the thermo-hydraulic performances. The numerical results show that, the largest Nusselt number occurs at a dislocation angle of 60°. The friction factorfis relatively larger than that when the dislocation angle is 0°, and it exhibits an obvious increment with the dislocation angle. From the value of performance evaluation criterion (PEC), the best thermo-hydraulic performance is achieved at a 60° dislocation angle. The underlying mechanisms are analyzed in terms of flow field and temperature field.

Use of baffles in jet impingement systems in presence of initial cross-flow disturbs boundary layer that results in rise in heat transfer. Two configurations of baffle assisted impingement systems were considered and a comparative study on heat transfer and pressure drop is carried out based on operating parameters such as baffle clearance, blow ratio and h/D ratio using commercially available CFD package. Numerical predictions showed that both heat transfer and pressure drop in segmented configuration were higher than louvered configuration for all blow ratio employed in this study. Parametric studies showed that, thermo-hydraulic performance parameter is higher only for louvered configurations at low blow ratio. When cross-flow velocity is comparable with jet velocity, segmented baffles resulted in relatively higher thermo-hydraulic performance because of its higher heat transfer rate relative to the incurring pressure drop. An increase in clearance proportionally increases performance parameter. However, as jet to plate distance increases, thermo hydraulic performance declines significantly.

Trefoil-hole baffles have good thermo-hydraulic performances as the support of heat pipes, however the published research paper is relatively limited. The present paper investigates the shellside thermo-hydraulic characteristics of shell-and-tube heat exchanger with trefoil-hole baffles (THB-STHX) under turbulent flow region, and the variations of shellside Nusselt number, pressure loss and overall thermo-hydraulic performance (PEC) with Reynolds number are obtained for baffles of varied pitch with the numerical method. CFD results demonstrate that the trefoil-hole baffle could enhance the heat transfer rate of shell side effectively, and the maximal average Nusselt number is augmented by ～2.3 times that of no baffle, while average pressure loss increases by ～9.6 times. The PEC value of shell side lies in the range of 16.3 and 73.8 kPa-1, and drops with the increment of Reynolds number and the decrement of baffle pitch, which indicates that the heat exchanger with trefoil-hole baffles of larger pitch could generate better overall performance at low Reynolds number. Moreover, the contours of velocity, turbulent intensity and temperature are presented for discussions. It is found that shellside high-speed jet, intensive recirculation flow and high turbulence level could enhance the heat transfer rate effectively. Besides good performance, THB-STHXs are easily manufactured, thus promise widely applied in various industries.

L’efficacité énergétique des composants et systèmes thermiques, l’amélioration et le développement de nouvelles technologies sont des enjeux majeurs aujourd’hui. Dans ce contexte général, les travaux de cette thèse s’inscrivent dans une perspective d’amélioration des performances thermiques et de mélange d’échangeurs-réacteurs multifonctionnels qui, plus que jamais, sont des composants clés. Pour atteindre cet objectif, une technique d'intensification passive a été explorée. Elle implique l'application de deux types de macro-déformations pariétales sur les parois d'un tube annulaire en écoulement laminaire. L’étude s’est tout d'abord concentrée sur la caractérisation des écoulements secondaires créés par chacune des déformations appliquées séparément sur l’intensification des transferts. Ensuite, une combinaison de déformations radiales successives et alternées sur la paroi externe, associées à une géométrie engendrant un mouvement de swirl sur la paroi interne a permis d'augmenter significativement le mélange, grâce à l'apparition d'advection chaotique dans l'écoulement. La compréhension des mécanismes physiques mis en jeux s’est appuyée sur une analyse numérique des champs locaux thermiques et hydrauliques, sur l’identification des structures tourbillonnaires, sur les sections de Poincaré, ainsi que sur la détermination des performances thermo-hydrauliques et de mélange au niveau global et local. Une évaluation expérimentale du comportement hydraulique a été aussi effectuée par le biais de la méthode de distribution des temps de séjour, ce qui a permis de valider en partie le modèle numérique choisi dans cette étude. Enfin, la dernière partie de l'étude a été consacrée à l'application des concepts d'intensification étudiés au cas d'un capteur solaire thermique à concentration
The energy efficiency of thermal components and systems, as well as the improvement and development of new technologies, are major challenges today. In this general context, the work of this thesis is aimed at improving the thermal performance and mixing of multifunctional heat exchanger-reactors, which are more than ever key components. To achieve this goal, a passive intensification technique has been explored, involving the application of two types of macro-wall deformations on the walls of a laminar flow annular tube. The study initially focused on characterizing the secondary flows created by each of the deformations applied separately in order to enhance heat transfer.Subsequently, a combination of successive and alternating radial deformations on the outer wall, coupled with a geometry that induces swirl motion on the inner wall, significantly increased mixing by promoting chaotic advection within the flow. The understanding of the underlying physical mechanisms relied on numerical analysis of local thermal and hydraulic fields, identification of vortical structures, Poincaré sections, as well as the determination of thermo-hydraulic and mixing performance at both global and local levels. An experimental evaluation of hydraulic behavior was also conducted using the residence time distribution method, partially validating the chosen numerical model in this study. Finally, the last part of the study was dedicated to the application of the intensification concepts studied to the case of a concentrated solar thermal collector

Automobile radiator is the key component in the cooling system of the engine for a car. There are some problems will be caused if the thermo- hydraulic performance overheating such as the parts soften, abrasion, amount of oil consumption and the power decrease. However, how to enhance the thermo-hydraulic performance of automobile radiators is a key problem in the vehicle industry. The methods of enhance the automobile radiator performance such as change the angle of the fin and shape, change the working fluid and coated surface. But the method of the coated surface cannot enhance the thermo-hydraulic performance for automobile radiator. Therefore, the objectives of this study will use carbon nanocapsules material coating to enhance the automobile radiator performance without increase the principle. And also enhance the anti-fouling and the corrosion resistant features of the automobile radiator. This study used carbon nanocapsules material coating to enhance the automobile radiator performance of wave-fin and plate-fin. And use the wind tunnels, thermostatic water bath, data miner and differential pressure gauges to measurement the automobile radiator performance of coated and uncoated carbon nanocapsules material. Finally, investigate the effects of automobile radiator thermo-hydraulic performance in different air-side Reynolds number (Rea=0~6214.2) and water-side Reynolds number (Rew=1222.8~5502.8). The results show that, the averaged heat transfer performances of wave-fin radiator with coating the carbon nanocapsules materials have 8-23% higher than without coating. The averaged heat transfer performances of plate-fin radiator coating the carbon nanocapsules materials have 5-17% higher than without coating. When the air-side flow field is laminar, the plate-fin of automobile radiator without coating which heat transfer performance will higher than wave-fin automobile radiator without coating (increase about 9%). When the air-side flow field is turbulence, the wave-fin of automobile radiator without coating which heat transfer performance will higher than plate-fin of automobile radiator without coating (increase about 12%). When the air-side flow field is laminar, the plate-fin of automobile radiator with coating which heat transfer performance will higher than wave-fin of automobile radiator with coating (increase about 5%). When the air-side flow field is turbulence, the wave-fin of automobile radiator with coating which heat transfer performance will higher than plate-fin of automobile radiator with coating (increase about 16%).

In recent years,the issue of saving energy and carbon reduction has been paid more and more attention. The heat exchanger is based on the heat transfer between the fluids to achieve the purpose of reducing the load. Plate fin-and-tube heat exchagers are widely used in several areas, such as heating, ventilating, air conditioning and refrigeration system. However, the geometries of plate fin and tube heat exchanger influence the flow field characteristics greatly and are the main reason for determining the effectiveness of the heat exchanger. In this study, the heat transfer performance and pressure drop of the air side are simulated by using Computational Fluid Dynamics,CFD. The turbulence model is simulated by k-ω and the simulation results are compared with literature. According to the comparison of results, the reasonable agreement is found between the simulation and experimental data, revealing the accuracy of the CFD simulation. For the purpose of optimizing heat exchanger, this research use Taguchi analysis to find the optimal combination of parameters. The geometrical parameters that affect the performance of the heat exchanger, such as tube arrangement, longitudinal pitch, transverse pitch and fin pitch. The increase in the longitudinal pitch and transverse pitch causes a decrease in the heat transfer and pressure drop performance as the flow becomes less compact. The effect of fin pitch on the heat exchanger shows the opposite performance to that of the longitudinal and transverse pitches. According to the results, the optimal combination of parameters is the in-lined configuration, the longitudinal pitch of 38.1mm, the transverse pitch of 35.4mm, and the fin pitch of 1.53mm.

A computational simulation of the thermo hydraulic performance of a trapezoidal Off Set Strip Fin (OSF) is performed. The simulations are carried for Reynolds number ranging from 300 to 9000 considering three-dimensional conditions (3D). Calculations were developed assuming a constant flow. Colburn factor j, and the friction factor f, were calculated. Uniform temperature condition is assumed at the solid surface and at the inlet. The results have been compared with studies made by Kays and London, (1984), Manglik and Bergles (1990), and Muzychka and Yovanovich, (2001). According to the obtained results, it can be concluded that Computational Fluid Dynamics (CFD) is able to explore the behavior and performance of this kind of fin, showing that the hydraulic performance is well represented by correlations widely used in literature, while thermal performance seems to be under predicted.

Abstract In this work, an investigation of the heat sink performance employing sinusoidal microchannels embedded with pin fins was conducted. The effect of the sine wave frequency, the pin fins’ diameter, and the hydraulic diameter of the microchannel are studied. The results are quantified in terms of thermal resistance and pressure drop. The study was done using Reynolds numbers varying from 250 to 2000. As Reynolds number increases, the heat sink’s thermal resistance decreased while the pressure drop increased accordingly for all scenarios. The sinusoidal microchannels showed better performance — lower thermal resistance — but with the cost of higher pressure drop compared to the straight microchannel heat sink. The heat sink’s performance was improved by increasing the frequency, diameter of pin fins, and hydraulic diameter; however, this reduction in thermal resistance was associated with an increase in pressure drop. The reduction in thermal resistance of the different configurations of the sinusoidal microchannels was between 17% and 69% compared to the straight microchannel heat sink.

Open cell metal foam offers an interesting combination of materials properties from a heat exchanger point of view such as a high specific surface area, tortuous flow paths for flow mixing and low weight. A heat exchanger design with metal foams is studied in this work, aimed at low airside pressure drop. It consists of a single row of Al tubes covered with thin layers (4–8 mm) of metal foam. Through wind tunnel testing the impact of various parameters on the thermo-hydraulic performance was considered, including the Reynolds number, the tube spacing, the foam height and the type of foam. The results indicated that if a good metallic bonding between the foam and the tubes can be achieved, metal foam covered tubes with a small tube spacing, small foam heights and made of foam with a high specific surface area potentially offer strong benefits at higher air velocities (> 4 m/s) compared to helically finned tubes. The bonding was done by conductive epoxy glue and was found to have a strong impact on the final results, showing a strong need for a cost-effective and efficient brazing process to connect metal foams to the tube surfaces.
