Microscale Heat Transfer

The study of non-linear transport in gas flows associated with micro and nanodevices has emerged as an important topic in recent years. In the field of microscale heat transfer, convective heat transfer in slip-flow regimes in simple geometries like channels and tubes is a key problem. Constant-wall-temperature convective heat transfer in microscale tubes and channels has been studied recently using analytical solutions to an extended Graetz problem. In addition, much effort has been put into the development of computational models beyond the theory of linear constitutive relations for the analysis of microscale gas flow and heat transfer, since the Navier-Stokes-Fourier theory is not known to remain valid in the flow regimes of large Knudsen number. The objective of the present paper is to investigate microscale heat transfer where temperature jump is the dominant phenomena. The emphasis will be on the qualitative features of microscale heat transfer, for example, enhancement or reduction of heat transfer in microscale geometries. General features of computational models such as the full kinetic model and fluid dynamics model are also discussed.

Experimental investigation aimed at characterizing fluid flow and heat transfer in mini channels is presented in this paper. Forced convection flow of water through rectangular mini channels with hydraulic diameters in the range 0.28–3.67 mm and aspect ratio (H/W) 0.33–2.5 was investigated, for different flow regimes, and correlations were proposed for the flow friction and heat transfer characteristics. Fully turbulent convective heat transfer was achieved in mini channels at lower Reynolds numbers compared to conventional sized channels. Critical Reynolds number for flow transition was found to decrease with the hydraulic diameter. A comparison of the results in mini channels and microchannels indicate common trends, especially in the dependence of flow transition on the hydraulic diameter. Experimental results were compared with predictions for flow and convective heat transfer in conventional sized channels. Based on the finding that the frictional and heat transfer characteristics of the mini channels deviated from the predictions, a few new correlations are proposed for the laminar and turbulent flow regimes.
