| Abstract: | A method for the calculation of the velocity and pressure fields was proposed. Based on the 3D flow field computation, a method for the performance estimation and the energy losing analysis for hydraulic turbines was discussed. An illustrative example was given in the flow field computation of the draft pipe to demonstrate the proposed method. The distributing of the axial velocity and its pressure were showed by the CFD technique. The results indicate that traditional model test can be replaced with the numerical simulation of the 3D flow inside hydraulic turbines in this way so that the design period can be shortened and the cost reduced. |
