摘要

本文在较大的克努森数范围内分析了稀薄气体在平面周期性矩形通道（膜）系统中的流动。基于Shakhov s模型碰撞积分方程和可压缩介质的Navier-Stokes方程的动力学方程的数值解对该问题进行了研究。重点计算了质量流量与渗透率、相对通道长度和稀薄参数的关系。

Numerical Analysis of Rarefied Gas Flow through a Periodic System of Channels

Rarefied gas flows through a planar periodic system of rectangular channels (membrane) are analyzed in a wide range of Knudsen numbers. The problem is studied based on the numerical solution of the kinetic equation with the Shakhov S-model collision integral and the Navier–Stokes equations of the compressible medium. The main attention is paid to the calculation of the mass flow rate as a function of the permeability, the relative channel length, and the rarefaction parameter.
