Abstract
The theoretical Poiseuille flow and the thermal creep flow for rarefied gases in a long, rectangular channel are computed using the BGK model of the Boltzmann equation and diffuse scattering from the walls. These results are compared with available experimental data for Poiseulle flow. The present work provides a way to compute flow in a rectangular channel that is estimated to be accurate to ±5% for common gases.This publication has 0 references indexed in Scilit:
