Inside Flow Field Analysis of Automobile Hydraulic Retarder

There is a new way, using FLUENT--a computational fluid dynamics software, to analyze the inside flow field of hydraulic retarder instead of using one-dimension flow theory. In the simulation process, the inside flow field is assumed whole fluid-filled. And the moving areas use sliding mesh model while the turbulence model chooses standard two equations model. Finally, there are analysis of the pressure, velocity distribution and torque characteristics. Then compare the simulate results with the trial results to verify the feasibility of treatment method.
