“…In the case of microscale devices, the impact of viscous dissipation is significant even for lowvelocity flows because of the small dimensions. Numerous researchers [6][7][8][9][10] reported the effect of viscous dissipation on heat transfer during the fluid flow in various channels both theoretically and experimentally. In addition, the heat transfer characteristics in microdevices with viscous dissipation was analyzed by employing asymmetric heat fluxes at the surface [11][12][13][14].…”

The effect of viscous dissipation and rarefaction on heat transfer characteristics of hydrodynamically and thermally fully developed flow between parallel plates with constant heat flux conditions is analyzed. Three different types of heat flux boundary conditions, i.e., both plates kept at different constant heat fluxes, both plates kept at equal constant heat fluxes, and one plate insulated, are applied. In all cases, closed form expressions are obtained for the temperature distribution and Nusselt number. Viscous dissipation, rarefaction, and heat flux ratio are found to influence the heat transfer substantially. The present predictions are verified for the cases which neglect the microscale and viscous heating effect. The obtained results are in good agreement with other analytical results.

“…Though we take our analysis in the micro scales of length we do not use the slip boundary condition since the Knudsen number for the working fluid is ≤ 0.001. This condition is recognized [24,25] as the one which assures the validity of the continuous hypothesis for describing the transport phenomena in the system and it allows us to despise the slip of velocity at the plates. We calculate the Knudsen number through the expression…”

Abstract:The heat transfer problem of a zero-mean oscillatory flow of a Maxwell fluid between infinite parallel plates with boundary conditions of the third kind is considered. The local and global time-averaged entropy production are computed, and the consequences of convective cooling of the plates are also assessed. It is found that the global entropy production is a minimum for certain suitable combination of the physical parameters and a discrete set of values of the separation between the parallel plates. The transferred heat at the plates also shows minima in the same discrete set of values of the plates separation.
