| Abstract: | With the method of model test and numerical simulation, optimum design for the bottom flow passage's shape of the rectangular orifice surge chamber is studied. Based on the model test, optimum design is supplied. Then the flow under three operating conditions of the original design and optimum design is simulated numerically. The numerical results agree with the results of the model test. Both results of the numerical simulation and the model test verify that the optimum design can make the flow smoother, decrease the head loss and increase the efficiency of the power generation compared with the original design. |
