| Abstract: | To improve the efficiency of torque converter,a torque converter equipped in off-road car W305 was modeled in detail and its internal flow was calculated using the program CFD.Based on the numerical results,the characteristic and distribution of flow field were analyzed to find out the factors affecting the efficiency of torque converter.For validating the accuracy of results calculated by CFD,the flow field of stator was experimentally researched by laser Doppler anemometer(LDA).The obtained data was analyzed and compared with numerical results.It is proved that they are in good agreement with each other,and the design of torque converter can be guided by numerical results in CFD. |
