Analysis of heat transfer in the slip flow region between parallel plates

Abstract

In this paper, an analytical study has been carried out to investigate the effect of viscous dissipation on heat transfer characteristics in the slip regime for the fluid flowing between two infinite fixed parallel plates. The flow is assumed to be hydrodynamically and thermally fully developed with constant properties. In the present analysis, one wall is considered as adiabatic and the other one is kept at constant heat flux. Closed form expressions are accomplished for the Nusselt number as a function of Knudsen number and Brinkman number. The limiting condition of the present prediction for Kn = 0, Kn2 = 0, and Br = 0 is presented to verify the results. © Springer India 2017.
