Heat Transfer in Cavities: Configurative Systematic Review

Abstract

This study is a systematic review of research on heat transfer analysis in cavities and aims to provide a comprehensive understanding of flow and heat transfer performance in various kinds of cavities with or without the presence of fins, obstacles, cylinders, and baffles. The study also examines the effects of different forces, such as magnetic force, buoyancy force, and thermophoresis effect on heat transfer in cavities. This study also focuses on different types of fluids, such as air, water, nanofluids, and hybrid nanofluids in cavities. Moreover, this review deals with aspects of flow and heat transfer phenomena for only single-phase flows. It discusses various validation techniques used in numerical studies and the different types and sizes of mesh used by researchers. The study is a comprehensive review of 297 research articles, mostly published since 2000, and covers the current progress in the area of heat transfer analysis in cavities. The literature review in this study shows that cavities with obstacles such as fins and rotating cylinders have a significant impact on enhancing heat transfer. Additionally, it is found that the use of nanofluids and hybrid nanofluids has a greater effect on enhancing heat transfer. Lastly, the study suggests future research directions in the field of heat transfer in cavities. This study’s findings have significant implications for a range of areas, including electronic cooling, energy storage systems, solar thermal technologies, and nuclear reactor systems.

Entropy Production Analysis in an Octagonal Cavity with an Inner Cold Cylinder: A Thermodynamic Aspect

“…Their findings confirmed that using a multi-blade dynamic modulator enhanced the HT efficiency of the cavity. In 2023, Saha et al [26] presented a configurative systematic review of the research on heat transfer in cavities. The systematic review covered a wide range of topics related to cavity heat transfer, including natural or mixed or forced convection, radiation, and magnetic field effects.…”

“…The effect of radiative heat transfer, viscous dissipation, and magnetic force are neglected in this study. The two-dimensional Navier-Stokes equations, which govern the fluid flow and the energy that governs the HT, are presented in a dimensional format, as below 39,50 :…”

“…The effect of radiative heat transfer, viscous dissipation, and magnetic force are neglected in this study. The two‐dimensional Navier–Stokes equations, which govern the fluid flow and the energy that governs the HT, are presented in a dimensional format, as below 39,50 : $$$\frac{\partial u}{\partial x}+\frac{\partial v}{\partial y}=0,$$$ $$$\rho \left(u\frac{\partial u}{\partial x}+v\frac{\partial u}{\partial y}\right)=-\frac{\partial p}{\partial x}+\mu \left(\frac{{\partial }^{2}u}{\partial {x}^{2}}+\frac{{\partial }^{2}u}{\partial {y}^{2}}\right),$$$ $$$\rho \left(u\frac{\partial v}{\partial x}+v\frac{\partial v}{\partial y}\right)=-\frac{\partial p}{\partial y}+\mu \left(\frac{{\partial }^{2}v}{\partial {x}^{2}}+\frac{{\partial }^{2}v}{\partial {y}^{2}}\right)+\rho g\beta (T-{T}_{0}),$$$ …”

“…The results indicated that the movement direction of the attached fins has an impact on both the convective flow pattern and its intensity. Saha et al 39 systematically reviewed HT analyses within cavities, aiming to comprehensively grasp flow and HT phenomena amidst diverse obstacles. The study underscored significant HT enhancement within cavities featuring elements such as fins and rotating cylinders.…”
