As application examples,the coupling algorithm was used in calculation of flow field in the multi-impeller of the torque converter and the hydrodynamic coupling under different rotation speeds.

The unsteady flow field of the hydrodynamic coupling is computed under different quantity of liquid, by using the methods of large eddy simulation (LES), flow control equation coupled solution,sliding mesh method for multi-flow regions in CFD software.

The variable speed hydrodynamic coupling mainly depends on the kinetic energy which is made by the liquid in the impeller to transfer the power.
