Analysis of Chamber Shape’s Influencing on Axial Force in Hydrodynamic Coupling

In order to research the law of chamber shape’s influencing on Axial Force in Hydrodynamic Coupling, flow field and axial force are numeric simulated at different chamber shapes in full filling rate by using separation solver, realizable k~e model and PISO algorithm with CFD. The result shows that chamber shape has a greater impact on the axial force, and the influence weaks with the increase of speed ratio.
