Özet

The effect of high-Prandtl number on steady fully developed microscale flow and heat transfer between two parallel plates exposed to a constant heat flux is investigated analytically in this study. The Prandtl number over several orders of magnitude (5 < Pr <103) as well as different Knudsen number (0 < Kn <0.1) and different modified Brinkman number (-0.1 < Br <0.1) are considered. The momentum and energy equations are solved for first order boundaries of slip velocity and temperature jump. The influences of the Prandtl number, Knudsen number and Brinkman number on the temperature distribution and heat transfer characteristics are discussed.
