| Abstract: | Three hydraulic models for roto-jet pump,i.e.,single closed impeller,single semi-open impeller and double semi-open impeller,are designed in this work.Based on CFD,and by means of ANSYS CFX software,the 3D numerical simulations of flow field for the three hydraulic models are performed,and the pressure distributions and velocity fields are obtained.The variation of head,shaft-power and hydraulic efficiency with flow rate for the three hydraulic models are calculated and analyzed.The simulation and the perfo... |
