Hydrodynamic Design of Pump Diffuser Using Inverse Design Method and CFD
A new approach to optimizing a hydrodynamic design of pump diffuser is presented, based on a three-dimensional inverse design method and a Computational Fluid Dynamics (CFD) technique. The blade shape of the diffuser was designed for a specified distribution of circulation and a given meridional geometry at a low specific speed of 0.109 (non-dimensional) or 280 (m3 /min, m, rpm).
