Résumé
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 arbitrary-Lagrangian-Eulerian method. The computations were performed for a wide range of Reynolds number and Mach number and for both `no heat conduction' and isothermal flow conditions. 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 and was compared with available experimental results. It was found that f·Re is mainly a function of Mach number and is different from the incompressible value of 96 for parallel-plate channels.
