“…In order to comprehensively consider relevant factors, its scope of application is small and can not be widely used. In reference [5], Morgan et al Mainly studied how to use the finite volume formula to analyze the thermal performance of cylindrical radiators with different microchannel shapes and working fluids. Experiments show that this method can accurately and clearly enhance the thermal performance of cylindrical radiators.…”

In order to improve the accuracy of numerical simulation of magnetic fluid thermal coupling of cylindrical heat source, a numerical simulation method of magnetic fluid thermal coupling of cylindrical heat source based on LBM grid algorithm was studied. Based on the theoretical model of natural convection and radiative heat dissipation of cylindrical heat source, the boundary conditions were set, and the thermal coupling performance of flow field and temperature field in the process of natural convection and radiative heat dissipation of cylindrical heat source was simulated by LBM grid algorithm. Simulation results show that the relative error between simulation results and experimental results is less than 1.5%. The results show that this method can accurately simulate the magnetofluid-thermal coupling of cylindrical heat source. With the increase of Rayleigh number, different numerical solutions appear: steady state solution when Rayleigh number is 105, periodic oscillation solution when Rayleigh number is 106, chaotic solution when Rayleigh number is 107.

“…Micro-and nano-channels are the essential part of microfluidic and nanofluidic devices in which different phenomena such as surface tension and capillary effects [1], and rarefaction effects happen. Miniaturization of the systems can bring different benefits depending on the application, some of which are lower reagent consumption, faster and more precise bio-chemical reactions, precise control over flow characteristics [2][3][4][5]. The focus of the present study is on gas flows at micro-scales where gas rarefaction effects and gas-surface interactions are critical.…”

In today’s complex micro–electro–mechanical systems (MEMS), investigation of flow through irregular micro/nanochannels, such as bended channels, variable cross-sectional area channels, and those with rough surfaces, can contribute considerably to efficient designing of the microdevices and to gain a better understanding of the flow structure in these geometries. The present paper reviews the prominent studies published in literature on rarefied gas flow through these types of complex geometries. The main focus of the study is to explore the physical aspects of the findings and the analyses provided in support of the results. Finally, the areas in which a gap exists in literature and could be subjects of future studies are introduced.
