Poiseuille flow and thermal creep of a rarefied gas between parallel plates

摘要: A numerical solution of the Boltzmann equation with Bhatnagar‐Gross‐Krook model is obtained for Poiseuille flow and thermal creep a rarefied gas between two parallel plates. The results are in fair agreement wth experimental data Dong predict Knudsen minimum volume rate. present approach transpiration formula analyzed on basis elementary kinetic theory gases as density decreases agree well Maxwell's continuum range low number. effect velocity profile very large, especially at layer near plate.
