Abstract

The practical utility of a 3D inverse viscous method is demonstrated by carrying out a design modification of a first-stage rotor in an industrial compressor. In this design modification study, the goal is to improve the efficiency of the original blade while retaining its overall aerodynamic, structural and manufacturing characteristics. By employing a simple modification to the blade pressure loading distribution (which is the prescribed Sow quantity in this inverse method), the modified blade geometry is predicted to perform better than the original design over a wide range of operating points, including an improvement in choke margin.
