3D/1D simulation of vehicle cooling system and its wind tunnel test research
For the development of a sedan,1D and 3D joint simulation was carried out and verified with the help of wind tunnel test of the whole vehicle.Cooling module gas flow was obtained by three-dimensional simulation,the system water temperature was solved by one-dimensional simulation,and ultimately test calibration was conducted by the wind tunnel.The deviation of the simulation results from the wind tunnel test was less than 2%,which confirmed the validity of the 3D/1D simulation;the accuracy of the heat dissipation input had a great influence on the simulation results.When the heat dissipation increased by 14.2 kW,the outlet water temperature of engine increased by 10.7℃.
