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.
