The problem is going to simulate the airflow inside an axial flow compressor (Rotor Nasa 37). The present model consists of a series of blades for an axial-flow compressor connected to the central axis within a cylindrical area. To simplify the simulation model, only one row of rotating blades is drawn on the central rotor of the compressor. The blades rotate around the central axis at a rotational speed of 14043 rpm.

Therefore, to simulate the present model, the Frame Motion technique with the mentioned rotational speed has been used to simulate the airflow in the space around the compressor blades, so that the blades are assumed to be fixed (without rotational speed), and the air around the blades has a rotational speed equal to the rotational speed of the compressor rotor. Also, for the compressor blade wall, the boundary condition of the moving wall with zero rotational speed has been used compared to the surrounding area. Since the compressor nature is based on the pressure increase of the fluid, the pr
