Rotating speed and diameter of the shaker were two independent variables in the simulation.
To evaluate the variable hydrodynamic condition in terms of the erosion from the flow acting on the surface of an MHV, the instantaneous viscous shear stresses can be obtained by the CFD model established in this work.

At present, the rapid development of computational fluid dynamics (CFD) provides a strong research method to fan’s optimization design, and the widely use in engineering plays a more and more important role in saving money and shortening development cycle[1].
The general CFD analysis software is highly professional.
This is because the simulation has neglected parts of mechanical loss caused by bearing transimission, and the characteristics of numerical simulation also led to the result.
So it is very appropriate to research the fan with the simulation method.

With Eulerian Method of Moment (MoM) solvers for the CFD simulation of multi-phase fluid flow, the positions of bubbles or droplets are not modeled explicitly, but through scalar fields of moments.
In such simulations, the exact positions of bubbles are considered uncertain.

The Meshing and Numerical Calculation Condition ICEM CFD software is pre-processor provided by the FLUENT company, which contains powerful geometric modeling capabilities and powerful meshing tools, and it could generate high-quality mesh model containing boundary layer, which could be directly used by FLUENT.
Based on the idea of ICEM CFD meshing, fluid model is cut into a number of regular geometric bodies, in order to improve the mesh quality; model is divided into hexahedral meshes according to different body characteristics, meshing with Cooper.

The simulation results does not appear divergent which indicate how stable of FVM to solve the equation.
Furthermore, temperature field distribution of hydrostatic bearing which obtained form numerical simulation is accord with realistic which proved the reliability of the research method.

Based on theory of fluid-solid interaction (FSI), a three dimensional finite element computational model of blade wheel in a vehicular hydraulic retarder was built considering accurate fluid pressure and centrifugal stress with unidirectional FSI method, and viscous numerical simulation of computational fluid dynamics and then strength analysis were implemented, and the reliability of blade wheel was verified.
While for CFD and CSD analysis, the computational grids were quite different and nodes of them can not be coincident generally, so the calculation information can not be exchanged directly, then the automatic information mapping mechanism should be adopted based on ANSYS/Workbench platform involving CFX and mechanical modular.
According to the cyclosymmetric of wheels, a group of passages with one rotor and stator passage was selected as CFD computational model shown in Fig.3, and grid and boundary conditions were applied to it.
Fig.3 Model group of CFD computation with rotor and stator passages When hydraulic retarder works, especially applied with centrifugal stress rotor load is larger than stator load throughout, so the strength of rotor should be paid more attention to, and for the cyclosymmetric feature of rotor blade wheel of hydraulic retarder, solid geometry model and computational FEA model of 1/20 rotor blade wheel were shown in Fig.4.
The constraints were defined as follows: (1)periodic symmetric restrain was applied on slicing planes of 1/20 model; (2)displacement restrain was applied at hub of rotor wheel; (3)fluid pressure load derived from CFD analysis was applied on the pressure and suction surface of blade; (4)rotating speed of 2200 r/min was applied to the whole rotor wheel model, while that of stator wheel is zero.
