Research status and development of torque converters in passenger vehicles

Abstract:

Firstly, new trends of research and applications of torque converters are overviewed in this paper. Then, the technology of measurement and numerical simulation of internal flow field, optimization and prediction of hydraulic performance as well as analysis of key design parameters of torque converters are discussed. Furthermore, the current research achievements are brought forth, such as parametric modeling of cascade system based on the non-uniform rational B-spline, modification of hydraulic prediction model based one-dimension flow theory according to the results obtained from computational fluid dynamic analysis and internal flow simulation in the turbomachinery based on the lattice-Boltzmann method. Finally, based on the current research achievements, the way to realize the technology of automated integration of cascade design and analysis is presented.
