CFD Calculation Method Improvement for Torque Converter after Coupling Point

Abstract:

This study, which uses CFD(computational fluid dynamics) and linear extrapolate and adds stator speed effect at coupling condition,can solve the problem that in the current CFD calculation way, the hydraulic performance of torque converter above the coupling point can not be accurately simulated. The method can reach the good result and provides the good contribution to the design of the torque converter in the companies.
