CFD method was adopted for simple surge chamber and impedance surge chamber by numerical simulation ,surge chamber resistance coefficient values were calculated with different split ratios ,and the simulation results and the experimental data were analyzed . The results showed , simulation and experimental curves were basically the same trend , numerical simulation and experimental values agree well ,therefore ,and the research can be initially determined that the method can be applied in the drag coefficient of the surge chamber .On this basis ,this method was applied in the simulation of practical power station surge chamber ,and through the calculation of hydraulic transition process ,the accuracy of the results was verified .CFD method can be applied in the design of surge chamber calculation .
