Abstract
Two-dimensional compressible momentum and energy equations are solved in a parallel-plate channel to obtain the effect of compressibility on gaseous flow characteristics in micro-channels. The numerical methodology is based on the Arbitrary-Lagrangian-Eulerian (ALE) method. The computations were performed for a wide range of Reynolds number and Mach number and for both adiabatic and isothermal flows. The results are presented in form of the product of friction factor and Reynolds number (f·Re) expressed as a function of both Reynolds number and Mach number. It was found that f·Re is mainly a function of Mach number and is different from the incompressible value of 96 for a parallel-plate channel. © 2002 by the author(s).
