Joint Simulation of Coupled Flow in Hydrodynamic Retarders and Its Hydraulic Control System

doi:10.3901/JME.2024.12.355

Abstract

Abstract: The complex flow characteristics of hydrodynamic retarder and its hydraulic control circuit is taken as research object. Aiming at the problem that traditional separated simulation of hydrodynamic and hydraulic components causes missing of internal interaction and deviation of simulation results, a joint simulation method is proposed based on 3D computational fluid dynamics(CFD) simulation of retarder chamber and 1D modeling of the hydraulic system. TCP/IP interface is utilized to realize data interaction between two simulation platforms so that a real-time, bidirectional dynamic interaction inlet and outlet boundary can be established. Using the proposed method, working characteristics of the retarder under the control of hydraulic system can be predicted. The deviation between the predicted results and the experimental results is less than 5%, and the deviation of the feedback pressure value caused by lack of fluidity between inlet and outlet can be avoided. The joint simulation method established in this paper provides an effective tool for studying the working characteristics of retarder and its hydraulic control system, and can be further extended to related application fields where complex flow and control is involved.
