Parameterized Integration of Hydrodynamic Torque Converter Pump Blade Based on Joukowsky Confor-mal Transformation
In this paper,the integrated method of wind turbine airfoil profile expression was introduced to study the blade profile geometry of LB46 adjustable guide vane hydraulic torque converter.Based on the principle of Joukowsky conformal transformation,the pump blade profile was modified and four different orders of fitting were carried out.Finally,the three fitting results were select-ed and the flow field of the torque converter was numerically calculated by using the computational fluid dynamics method.The pre-dicted original characteristic curve was in accordance with the experimental results,which verified the feasibility of the integrated method,and provided new thinking of the innovation of torque converter structure.
