Suction/Injection Effects on Pulsating Poiseuille Basic Gaseous Fluctuating-Micro-Flows

Abstract

The pulsating Poiseuille fluctuating-micro-flow where the fluid flow is initiated by sinusoidal pressure gradient is investigated in this study. The flow problem is modelled and the analytical solution is obtained. The effect of suction/injection and that of other leading flow parameters such as the frequency of the fluctuating driving force, the Knudsen number and the unsteadiness are analyzed. It is found from the study that the effect of suction and that of injection are observed to be opposite; suction leads to increase while injection leads to decrease in velocity of the moving fluid.
