Temperature Field Analysis on the Hydrodynamic Retarder of Heavy Vehicle

摘要：

　　According to the working characteristics of the hydrodynamic retarder,the hydrodynamic retarder D300 is chosen in this research.Based on three-dimensional flow theory,the internal temperature fields of hydrodynamic retarder with different liquid-filled ratios of 100%,75%,50%,25% are numerically simulated.The standard k-ε model is chosen as turbulent model for calculation.The SIMPLEC algorithm is chosen as velocity-pressure coupling algorithm and the second order upwind scheme is used as discrete method.The mixture multiphase model is used to calculate the unsteady gas-liquid two-phase flow in the condition of partial charging.Through simulating and analyzing,it provides an important theoretical basis for the heat exchange of the hydrodynamic retarder at different gears.
