Special Issue Information

Dear Colleagues,

Thermal management in energy systems provides performance enhancement and reliable operating conditions during the lifespan of energy-related products, for which many applications are possible in diverse systems, including photovoltaic panels, hydrogen storage, lithium-ion battery systems, thermal energy storage, and micro-electro-mechanical systems (MEMs) in addition to numerous convective heat transfer applications. Active, passive, and hybrid methods have been considered for thermal management in renewable and nonrenewable energy systems. In one of the available methods, nano-sized particles are used in heat transfer fluids, and this nanofluid technology has been successfully implemented for thermal management of diverse energy systems, including solar power, thermoelectric power generation, refrigeration, jet impingement heat transfer, and electronic cooling applications. In terms of geometry, surface modifications in the form of controlled corrugation waves and partitioning of various types, including deformable, rotating, or moving obstacles of various shapes, have also been considered together with nanofluids. Advanced simulation tools and experimental and numerical techniques have been developed to analyze the impacts of using magnetic fields and porous media with nanofluids for thermal management in devised thermofluid systems. Applications of thermal energy storage (TES) systems and phase change materials (PCMs) are also a good option for thermal management in systems such as related to the cell temperature of a PV panel and to increase its efficiency. In addition, nano-enhanced PCMs are used with metal foams and highly conductive fins to increase their effectiveness, which provides better thermal management options in energy systems via passive techniques.

The present Special Issue will focus on the application of various thermal management methods in diverse energy systems and present the most recent methods and advanced simulation tools. It represents a good opportunity for researchers to present their promising thermal management techniques as part of a collection. It is envisaged that this Special Issue will serve as an invaluable reference for researchers and engineers by detailing the recent advancements, applications, and future challenges in thermal management techniques.

This paper studied the cooling performance of a hot electronic chip using nanofluids (NF) mixed convection, implementing Buongiorno’s model of the NF simulation. The NF were assumed water-Al2O3 nanoparticles (NP) in the range of 0 to 4% of volume concentration. Six different problems of the combinations of three internal hot blocks, including triangular, square, and circular geometries, and two porous media, including sand and compact metallic powder, were numerically solved. To discretize the governing equations, a finite control volume method was applied. As most of the proposed correlations for the thermophysical properties of the NF were inaccurate, especially for thermal conductivity, a new predictive correlation was proposed using the multi-variable regression method with acceptable accuracy. It was found that the cooling performance improved with any increase in the NP loading. A higher nanoparticle concentration yielded better cooling characteristics, which was 11.93% for 4% volume. The sand porous medium also yielded a much higher value of the normalized Nusselt number (Nu) compared to the other medium. The entropy generation (EG) enhancement was maximum for the triangular hot block in a sand porous cavity. Full article

Single and double impinging jets heat transfer of non-Newtonian power law nanofluid on a partly curved surface under the inclined magnetic field effects is analyzed with finite element method. The numerical work is performed for various values of Reynolds number (Re, between 100 and 300), Hartmann number (Ha, between 0 and 10), magnetic field inclination (γ, between 0 and 90), curved wall aspect ratio (AR, between 01. and 1.2), power law index (n, between 0.8 and 1.2), nanoparticle volume fraction (ϕ, between 0 and 0.04) and particle size in nm (dp, between 20 and 80). The amount of rise in average Nusselt (Nu) number with Re number depends upon the power law index while the discrepancy between the Newtonian fluid case becomes higher with higher values of power law indices. As compared to case with n = 1, discrepancy in the average Nu number are obtained as 38% and 71.5% for cases with n = 0.8 and n = 1.2. The magnetic field strength and inclination can be used to control the size and number or vortices. As magnetic field is imposed at the higher strength, the average Nu reduces by about 26.6% and 7.5% for single and double jets with n greater than 1 while it increases by about 4.78% and 12.58% with n less than 1. The inclination of magnetic field also plays an important role on the amount of enhancement in the average Nu number for different n values. The aspect ratio of the curved wall affects the flow field slightly while the average Nu variation becomes 5%. Average Nu number increases with higher solid particle volume fraction and with smaller particle size. At the highest particle size, it is increased by about 14%. There is 7% variation in the average Nu number when cases with lowest and highest particle size are compared. Finally, convective heat transfer performance modeling with four inputs and one output is successfully obtained by using Adaptive Neuro-Fuzzy Interface System (ANFIS) which provides fast and accurate prediction results.

Abstract: Currently, numerous researchers obtained experimental and theoretical works to analyze nanofluid's impact in various forms of temperature exchangers. In any manufacturing implementations, thermal exchangers are critical mechanism. Nanofluids are a homogeneous mixture of tiny-sized solid particles submerged in regular fluid. A novel mathematical model (computing study) for Radiative unsteady three dimensional, transport applications and motile gyrotactic microorganism's rates in the bioconvectional Casson-type nanofluid by using the Cattaneo-Christov heat and mass flux model passed a stretchable cylinder with mixed convection is envisioned successfully in this numerical Scrutinization. Also, Novel aspects of Cattaneo-Christov and activation energy are taken into account. Additionally, Buongiorno's nanofluid model featured with interesting charectrstics of Brownian motion and thermophoritic diffusion aspects is discribed. For this purpose, nonlinear expressions monitoring the present flow model are transformed into higher-order ODE's by employing suitable transformation. The formulated differential system is further set up using a new innovative bvp4c built-in tool MATLAB with a shooting scheme. The results show that flow pattern was explored for a wide range of analyzed parameters. Computational outcomes of skin friction, heat and mass transformation, local microorganism's densty number are scrutinized numerically in Tables. Also, It is trusted that current communication results will provide as a helping source for upcoming nanotechnology improvements about individualities of swimming microorganisms subject to mixed convection flow induced by a cylinder. Keywords: casson nanofluid; stretching cylinder; Cattaneo-Christov model; activation energy; swimming bioconvective motile microorganism; bvp4c method.
