It has passage areas, flow, and performance of the machine. Typically, it flexible models for losses, deviation, blockage, etc., uses real is restricted to a specific machine type, turbine or compressor in a gas/liquid thermodynamics and handles flow and geometry at three single shaft configuration. Flow is often modeled using ideal, spanwise locations. It is applicable to both compressors and
