Numerical analysis of oscillatory Couette flow of a rarefied gas on the basis of the linearized Boltzmann equation

The unsteady motion of a rarefied gas between two parallel plates, one of which is oscillating in its plane, is studied based on the linearized Boltzmann equation for a hard sphere molecular gas. The detailed numerical solution for a wide range of gas rarefaction and oscillatory frequency is presented. The transition of the solution from low to high frequencies under various degrees of gas rarefaction is discussed.
