According to the CFD simulation results, the structures and positions of flow baffles in the draft-tube were optimized to obtain the uniform flow rate distribution in the quench zone, which were verified by experiments as well.
In order to highlight the effect of flow baffles on the flow rate in a quench tank, the CFD simulation has been carried out for the flow rate distribution without / with flow baffles, and the flow rates were measured by a UDV to verify the simulation results as well.
Results of CFD simulation.
In order to obtain the uniform flow rate distribution, CFD simulations had been performed for many design cases with different structures and positions of the flow baffles in the quench tank.

CFD is also a approximate calculation, this feature itself means it can not used to get a very exact root for torque converter real characteristic, it also need test to optimize simulation boundary[3].
(4) Model solver： Large eddy simulation is the top priority simulation solver due to its fast convergence speed and high accuracy characteristic for transient flow field[4]. 4 CFD Simulation and Test All the torque in individual wheel of torque converter is originated from circulation difference between inlet and outlet, in some curtain situation, the sum of all wheel torque will be zero
(1) It can predict based on the rule above that all the 3 wheels torque sum vector shall be zero during CFD simulation, this characteristic can be considered as a very important criterion which is used to evaluate simulation accuracy, if the torque sum vector is not zero, it mean there is calculation deviation from CFD, the smaller the deviation the more accuracy it is.

Study and numerical simulation on gas-solid two-phase characteristic of cyclone separator[D].

In the past decades, little research was carried on about the APR, especially the simulation studies.
In the present simulation, the shear-stress transport (SST) - turbulence model is usually adopted as the turbulence model.
Calculations with different mesh distributions and quantities are carried out to demonstrate that the simulation results are grid independent.
