Transient Flow Field Characteristics and Experimental Research of Super-flat Torque Converter
The internal flow field characteristics and torque conversion performance of a small-torus super-flat torque converter are studied.A three-dimensional model of the torque converter is established,the full flow channel is extracted,ANSYS Fluent is used for numerical simula-tion calculations to obtain the performance characteristics under different working condi-tions,and the accuracy of the numerical cal-culations is verified through bench tests of the torque converter.The pressure field analysis of the impeller shows that the pressure distribution on the surface of the pump wheel is relatively uniform,the turbine and guide wheel are sub-jected to high-speed oil impact at the inlet and the connection,forming a high-pressure area.As the speed ratio increases,the working point changes,causing the pressure on the surface of the impeller to weaken,but the location of the high-pressure area remains unchanged.
