Problem Description

The model represents a single-stage axial compressor comprised of two blade rows. The first row is the rotor with 16 blades, which is operating at a rotational speed of 37,500 rpm. The second row is the stator with 32 blades. The blade counts are such that the domain is rotationally periodic, with a periodic angle of 22.5 degrees. This allows you to model only a portion of the geometry, namely, one rotor blade and two stator blades. Due to the high Reynolds number of the flow and the relative coarseness of the mesh (both blade rows are comprised of only 13,856 cells total), the analysis will employ the inviscid model, so that ANSYS FLUENT is solving the Euler equations.
