Simulation and Optimization of Commercial Vehicle Dust Pollution Based on CFD
Aiming at the commercial vehicle in low speed driving,easy to raise dust and cause air pollution.The CFD simulation analysis model of the commercial vehicle was established,and the correctness of the simulation model was verified by experiments.By combining the DPM discrete phase model analysis method with discrete dynamics,the multiphase flow in the commercial vehi-cle outflow field was simulated numerically,and the mechanism of dust pollution was revealed.Therefore,different dust control schemes were proposed,and the optimization analysis was carried out by HyperStudysoftware to seek the best dust control scheme,and experiments were carried out to verify it.The results show that the number of dust particles is reduced by44.67%compared with the original vehicle by optimizing the fan position,replacing the"U-shaped"air shield and optimizing the size of the air guide plate,and the dust pollution phenomenon is obviously reduced on the premise of ensuring the heat dissipation performance.
