N2 - In order to study the influence of torque converter inlet and outlet radius, especially pump outlet radius, the traditional one-dimensional streamline theory and DOE were combined to analyze the parameter sensitivity. And the three-dimensional flow field simulation was adopted to validate the results of one-dimensional approach. The results showed that the pump outlet radius had a significant effect on stall torque ratio and pump torque coefficient. The pump torque coefficient increased and the stall torque ratio decreased with an increasing pump outlet radius. The sensitivity analysis results showed that the pump inlet radius had a great influence on the efficiency of torque converter. The results of both methods agreed well with each other and showed that the two methods were both effective. Decreasing pump outlet radius could reduce the pump load and increase stall torque ratio, and moreover, solve the problem of pump overload without much efficiency sacrifice.
