Temperature Field Analysis on the Hydrodynamic Retarder of Heavy Vehicle

Abstract:

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.
