All numerical evaluations executed with Cmap software reported here have been developed using most-recent thermodynamic theories and machine aeromechanical models in accordance with PTC10. Eight design variables were chosen from the control points for the Bezier curves which widely influenced the geometric variation; four design variables were selected to optimize the flow passage between the hub and the shroud, and other four design variables were used to improve the performance of the impeller blade. Generally initiated on trips on process parameters. As well, many design parallels exist between high-pressure blowers and compressors. ); hong … II.
