Abstract: Abstract This study deals with the numerical solution of a 2D unsteady flow of a compressible viscous fluid in a channel for low inlet airflow velocity. The unsteadiness is caused by a prescribed periodic motion of the channel wall. Instudy three different governing systems of equations are considered – Full system, Adiabatic system, Iso-energetic system. Unsteady flow fields for inlet Mach number $$M_{\infty } = 0.012$$ and frequency 100Hz are presented.
