Measures of Internal Flow Calculation Accuracy Improvement on Hydraulic Torque Converter

In order to improve the calculation accuracy of the hydraulic torque converter internal flow field and the characteristic parameters, YB355-2 torque converter was chosen as an example, the cross-section containing two leaves was selected as the computational domain and the mapping method was used to divide the torque converter channel into hexahedral mesh. To improve the quality of the mesh division, the measures such as manual adjustment and appropriate mesh refinement were also adopted. The torque converter internal flow field is calculated and analyzed to improve the convergence speed and calculation accuracy. It is of vital significance for the development of new hydraulic torque converter.
