Abstract: A nanofluid is a fluid that accommodates nanometer-sized particles (10–9 ), called nanoparticles. These fluids implement a colloidal suspension of nanoparticles in a base fluid. The nanoparticles used in nanofluids are frequently made of metals, oxides, carbides, or carbon nanotubes. Usual base fluids include water, ethylene glycol, and engine oil. In this program, silver-doped copper oxide is used as nanoparticles. This nanoparticle has been prepared by the green synthesis method. The radiator's job is to eliminate heat from the engine. The effect of using nanofluids in a vehicle radiator was investigated. Increasing the nanoparticle volume concentration leads to improved heat transfer. The radiator size using nanofluids is revised to lose the same heat as water. The simplest option is to treat the nanofluid as a fluid with changed properties. Then, all that is needed is to recalculate the fluid properties and use any CFD software to simulate flow and heat transfer. And writing a UserDefined Function (UDF) for CFD Modeling Using a C programme or a C function that can be dynamically loaded with ANSYS Fluent to enhance its standard features

Ultra-high cooling performance is a crucial requirement of many thermomechanical systems, such as microelectronic devices, engine cooling systems, nuclear power systems, chemical reactors, and refrigeration systems. Recent experimental results reveal the potential thermal properties of suspended nanometallics in conventional fluids. In this study, the facile synthesis of one-dimensional delafossite CuAlO2 nanowires by microwave hydrothermal treatment was presented. A novel type of nanofluid consisting of CuAlO2 nanowires suspended in distilled water at various volume fractions (0.0, 0.2, 0.4, and 0.6 wt%) was successfully synthesized using an easily scalable sonication method. The microstructures of as-synthesized CuAlO2 were investigated by adopting X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM), and field-emission scanning electron microscopy (FESEM). Furthermore, the thermal conductivity and specific heat capacity of water-loaded nanofluid were measured at different volume fractions and temperatures. The results reveal a significant increase in thermal conductivity with increasing CuAlO2 loading levels and temperatures. The obtained results propound the fact that water-loaded delafossite CuAlO2 nanowires-based nanofluid is a promising candidate for future industrial applications.

Nanofluids have been widely studied over the past decade due to their extremely promising findings in terms of thermal transfer improvement techniques. These fluids have a number of potential benefits, including enhanced thermal resistance and heat transfer characteristics. The current study examines the numerical behavior of the square cavity loaded with a nanofluid for thermal enhancement under three different base fluid conditions (water, water-EG mixture, and EG). This square cavity edge is maintained at a length of 8 cm. Side edges are kept at constant high and low-temperature conditions, and bottom sides are insulated. Additionally, it is found that when the base fluid's composition changes between EG to water, heat transmission is increased. The (hnfhbf/) ratio improves when the percent vol density of Al2O3 nanoparticle increases, and an increase of up to 4.5 percent is possible. Consequently, the paper concluded that the use of nanofluids aids in heat transfer enhancement.

In this study, investigation of convective heat transfer enhancement with the use of CuO–Polyaniline (CuO–PANI) nanocomposite basednanofluid inside vertical helically coiled tube heat exchanger was carried out experimentally. In these experiments, the effects of different parameters such as Reynolds number and volume % of CuO–PANI nanocomposite in nanofluid on the heat transfer coefficient of base fluid have been studied. In order to study the effect of CuO–PANI nanocomposite based nanofluid on heat transfer, CuO nanoparticles loaded in PANI were synthesized in the presence of ultrasound assisted environment at different loading concentration of CuO nanoparticles (1, 3 and 5 wt.%). Then the nanofluids were prepared at different concentrations of CuO–PANI nanocomposite using water as a base fluid. The 1 wt.% CuO–PANI nanocomposite was selected for the heat transfer study for nanofluid concentration in the range of 0.05 to 0.3 volume % and Reynolds number range of was 1080 to 2160 (±5). Around 37 % enhancement in the heat transfer coefficient was observed for 0.2 volume % of 1 wt.% CuO–PANI nanocomposite in the base fluid. In addition, significant enhancement in the heat transfer coefficient was observed with an increase in the Reynolds number and percentage loading of CuO nanoparticle in Polyaniline (PANI).

The current work investigates the performance of cylindrical-shaped sintered wick heat pipe at different orientations, numerically. The results are compared and validated with the experimental findings. The study is extended by using a nanofluid (comprising nano-Curo in deionized water) as a working fluid and the thermal performance of heat pipe with deionized (DI) water has been compared with that of heat pipe with nanofluid (containing various concentrations of CuO nanoparticles in DI water). During the investigation, the nanofluid with 1.0 weight fraction of CuO nanopaticles found to be optimum, which has produced the better results. The numerical analysis has been carried out to study the temperature difference, fluid velocity, and pressure drop of the sintered wick heat pipe using the commercial CFD software, Ansys Fluent R14.5. The computational results are observed to be much closer to the experimental data, and the vapor velocity at the heat pipe’s core has been determined to be 64.54% higher than the liquid flow over the wick structure. Interestingly, the heat pipe pressure drop has been reduced by adding CuO nanoparticles to the working fluid. Finally, the heat pipe loaded with a 1.0% concentration of nano-CuO in nanofluid has exhibited a notable reduction in pressure drop of 35.33%.

Free convective flow in a cubical cavity loaded with copper-water nanofluid was examined numerically by employing a non-homogeneous dynamic model, which is physically more realistic in representing nanofluids than homogenous ones. The cavity was introduced to a horizontal magnetic field from the left sidewall. Both the cavity’s vertical left and right sidewalls are preserved at an isothermal cold temperature (Tc). The cavity includes inside it four isothermal heating blocks in the middle of the top and bottom walls. The other cavity walls are assumed adiabatic. Simulations were performed for solid volume fraction ranging from (0 ≤ ϕ ≤ 0.06), Rayleigh number varied as (103 ≤ Ra ≤ 105), the Hartmann number varied as (0 ≤ Ha ≤ 60), and the diameter of nanoparticle varied as (10 nm ≤ dp ≤ 130 nm). It was found that at (dp = 10 nm), the average Nusselt number declines when Ha increases, whereas it increases as (Ra) and (ϕ) increase. Furthermore, the increasing impact of the magnetic field on the average Nusselt number is absent for (Ra = 103), and this can be seen for all values of (ϕ). However, when (dp) is considered variable, the average Nusselt number was directly proportional to (Ra) and (ϕ) and inversely proportional to (dp).

The current paper presents a numerical study of the magnetohydrodynamics natural convection and entropy production of Cu–water nanofluid contained in a porous annulus between a heated Koch snowflake and wavy cylinder with lower temperature with respect to the Koch snowflake. The numerical algorithm is based on the Galerkin Finite Element Method. The impacts of Rayleigh number (Ra = 103, 104, 105, and 106), Hartman number (Ha = 0, 25, 50, and 100), Darcy number (Da = 10−2, 10−3, 10−4, and 10−5), nanoparticle volumetric fraction (φ = 2%, 3%, 4%, and 5%), and the undulations number of the outer wavy cylinder (three cases) on the distributions of isotherms, streamlines, mean Nusselt number (Nuavg), as well as on total entropy production and Bejan number are thoroughly examined. The computational outcomes disclose that dispersing more Cu nanoparticles in the base fluid and creating a flow with higher intensity inside the annulus by raising the Rayleigh number bring about a boosted natural convective flow in the cavity, which improves the heat transmission rate. In addition, it can be noted that owing to the peculiar form of the heated Koch snowflake, nanofluid gets trapped between the angled parts, resulting in uneven temperature profiles with higher values in these places.

The introduction of toxic chemicals into the environment can result in water pollution leading to the degradation of biodiversity as well as human health. This study presents a new approach of using metal oxides (Al2O3 and SiO2) modified with a plasmonic metal (silver, Ag) nanoparticles (NPs)-based nanofluid (NF) formulation for environmental remediation purposes. Firstly, we prepared the Al2O3 and SiO2 NFs of different concentrations (0.2 to 2.0 weight %) by ultrasonic-assisted dispersion of Al2O3 and SiO2 NPs with water as the base fluid. The thermo-physical (viscosity, activation energy, and thermal conductivity), electrical (AC conductivity and dielectric constant) and physical (ultrasonic velocity, density, refractive index) and stability characteristics were comparatively evaluated. The Al2O3 and SiO2 NPs were then catalytically activated by loading silver NPs to obtain Al2O3/SiO2@Ag composite NPs. The catalytic reduction of 4-nitrophenol (4-NP) with Al2O3/SiO2@Ag based NFs was followed. The catalytic efficiency of Al2O3@Ag NF and SiO2@Ag NF, for the 4-NP catalysis, is compared. Based on the catalytic rate constant evaluation, the catalytic reduction efficiency for 4-NP is found to be superior for 2% weight Al2O3@Ag NF (92.9 × 10−3 s−1) as compared to the SiO2@Ag NF (29.3 × 10−3 s−1). Importantly, the enhanced catalytic efficiency of 2% weight Al2O3@Ag NF for 4-NP removal is much higher than other metal NPs based catalysts reported in the literature, signifying the importance of NF formulation-based catalysis.

In this study, we use numerical simulation method to discuss the conjugation cooling characteristics of Al2O3 nanofluid flow in a rectangular mini-channel. The aim of the present study is to discuss the results of two cases; the first case is to investigate the influence of buoyancy to the temperature and velocity in the mini-channel with/without thermal buoyancy effect. The second one is to investigate the effect of impeding the dramatic change in temperature under sudden pulsed power load with ceiling embedded with/without Micro-Encapsulated Phase Change Material (MEPCM). The geometries of the mini-channel are 4.016 mm in width, 1.004 mm in height, and 74.2 mm in length with the fin thickness of 2.008 mm. In order to describe the three dimensional heat transfer and fluid flows of the water-based suspensions in a single mini-channel, pseudo vorticity velocity formulation and energy equation are coupled to solve the temperature and velocity profile in the mini-channel. Numerical simulations for the laminar forced convection in mini-channel have been performed with parameters in the following ranges: the volumetric fraction of Al2O3 nanofluid, and ; the volumetric flow rate entering mini-channel, (equivalently, ); and the heat flux imposed on the bottom surface of the rectangular mini-channel . The diameter of the particle in Al2O3 nanofluid is 20 nm. The mini-channel is iso-flux heated with heat flux of and on the bottom, and the heat flux of the rectangular mini-channel is . The numerical results obtained for the channel with ARch = 0.25, ARbw =0.5, ARcw = 0.5, and Wsw = 0.5 clearly reveal that using the Al2O3 nanofluid to replace the pure water as the coolant in the rectangular mini-channel can reduce the bulk mean temperature in the fluid, enhance the averaged heat transfer coefficient, and reduce the overall resistance in the rectangular mini-channel, respectively. Al2O3 nanofluid has greater thermal conductivity than pure water and the thermal conductivity increases with increasing concentration. With the thermal buoyancy effect, the bulk mean temperature of the fluid is 1°C lower than that without the effect and the averaged heat transfer coefficient is enhanced about 5.2%. Furthermore, the thermal buoyancy effect reduces overall thermal resistance in the rectangular mini-channel about 3.5%. Plus, lower Reynolds number leads to greater difference in temperature and heat transfer coefficient.With sudden pulsed power load, the ceiling temperature with MEPCM is 2°C lower than that without MEPCM; however, the bulk mean temperature of the fluid reduces only 0.2°C.

The present study aims to investigate an experimental study concerning forced convective heat dissipation characteristics of Al2O3-water nanofluid flow in a mini-channel heat sink under steady/sudden-pulsed power load. Two multi-channel heat sinks featuring a length of 50 mm and a width of 25.1 mm were fabricated of oxygen-free copper with eight parallel mini-channels, each with an inlet cross-section of 1 mm in width and 3 mm in height with their ceiling embedded with or without a layer of a microencapsulated phase change material (MEPCM). The steady state experimental results obtained reveal that using the Al2O3-water nanofluid to replace the pure water as the coolant through the mini-channel heat sink can give rise to an enhancement of 41%, in the average heat transfer coefficient over that of using the pure water. In the aspect of incorporating the heat sink with its ceiling embedded MEPCM layer and hence the potential latent heat absorption effect, the steady state forced convection results reveal somewhat insignificant effects on cooling performance of Al2O3-water nanofluid. On the other hand, under the sudden-pulsed heat loads, the cooing effectiveness of using the Al2O3-water nanofluid in the heat sink with ceiling embedded MEPCM layer appears further uplifted in comparison with that without embedded MEPCM layer.

The design, analysis and modeling of solar energy-based water purifiers, commonly known as a solar still, which is based on the greenhouse effect, is the requirement of time as there is a scarcity of freshwater throughout the globe. The technology of purifying dirty water using solar energy is a promising solution for simplifying contemporary water scarcity as this technology does not create any bad effect on the surroundings, unlike conventional water purification technology, which creates a lot of polluting elements and ultimately has become problematic for the environment. Most solar energy-based water purifiers are self-sustainable, and they can be installed in remote locations where sunlight and source of impure water are available in abundance. This solar energy-based technology of water purification should perform better in hilly locations as the intensity of light is higher than the intensity of light in fields. The current chapter deals with the thermal modeling of different types of passive and active solar stills, including solar stills loaded with water-based nanofluids, followed by their energy and exergy analyses.

High heat loads of mechanical, chemical, and biomedical microsystems require heat exchangers which are very small, robust, and efficient. Nanofluids are dilute suspensions of nanoparticles in liquids, which may exhibit remarkable heat transfer characteristics, especially for heat removal in micro-devices. Minimization of entropy generation is potentially a design tool to determine best heat exchanger device geometry and operation. Focusing on microchannel heat sink applications, the thermal performance of pure fluid flow as well as different nanofluids (i.e., Al2O3+water and ZnO+EG) with different volume fractions are discussed. The local and volumetric entropy rates caused by frictional and thermal effects are illustrated for different coolants, geometries and operational parameters. The Feng-Kleinstreuer (F-K) thermal conductivity model, which consists of a base-fluid static part, kbf, and a new “micro-mixing” part, kmm, i.e., knf = kbf + kmm, was adopted in the thermal performance study of nanofluid flow in microchannels. In addition, two effective nanofluid viscosity models have been analyzed and are compared in the current study. In summary, the friction factor, pressure gradient, pumping power, local heat transfer coefficient, thermal resistance and entropy generation are evaluated for different nanofluids. The experimentally validated computational study provides new physical insight and criteria for design applications towards effective micro-system cooling.

A solar-energy based vapor absorption refrigeration system is potentially an excellent alternative air-conditioning system. However, there are several research challenges to ensure sufficient efficiency and reliability for ensuring widespread implementation. Integration of a parabolic trough solar collector utilizing a mixture of nanoparticles and water with a vapor absorption system has the potential to significantly enhance the efficiency of the system. Such a system makes use of the superior thermo-physical properties of the nanofluid compared to the base fluid. Moreover, the direct absorption phenomenon of solar radiation through interaction with the participating medium (nanofluid) results in a higher temperature rise of the medium in conjunction with higher operating efficiencies as well. At the same time there are certain challenges that need to be identified and addressed in the implementation of this novel concept. For instance, to make it reliable, the system further needs to be integrated with a thermal storage system which facilitates air-conditioning even during non-sunshine hours. Integration of vapor absorption refrigeration technology, parabolic trough with water-nanoparticles mixture as the absorbing medium and a thermal storage facility is the uniqueness of this design which under certain conditions and locations may prove to be an efficient and reliable substitute to the conventional electrical air-conditioning systems. In this particular study a space cooling application for approximately 100 Tons of refrigeration is studied. Hourly variation in sunlight as well as seasonal changes for temperate climate conditions is considered. Parameters such as the cooling load of the space, and waste heat produced by electronics are evaluated. The cooling system driven by the nanofluid-based concentrated parabolic solar collector is mathematical modeled and then the optimization is done by varying the nanoparticle size and volume fraction in order to obtain the best result for collector outlet temperature, thermal efficiency and optical efficiency.
