| Abstract: | Taking hydraulic loss and characteristic values of silt erosion as two objective functions and distribution pattern of velocity moment in circumferential section of the volute as design variables, a optimum design method for the volute of hydraulic turbine operated in silt laden water flow is discussed. It is proved by means of programming and designing that hydraulic losses and silt erosion in the volute designed could be decreased. |

| Keywords: | silt laden water flow volute hydraulic loss silt erosion optimum design objective function |
