Abstract: The torque converter W305 was modeled in detail and the internal flow field was computed using the program STAR-CD. To solve the interaction between the various stages with different speeds, the mixing plane model was used in the calculation. Based on the numerical results, the flow field characteristic in the pump wheel was analyzed. The velocity and pressure in the inlet and outlet of the pump wheel were analyzed and compared with correlative published experimental data. The external performance of the torque converter was also calculated and the results are in good agreement with the experiment.
