Numerical Simulation to Investigate Influence of Additional Devices on Aerodynamic Drag for Heavy-Duty Commercial Truck

Abstract:

To reduce the aerodynamic drag coefficient of a heavy-duty commercial truck made in China, the aerodynamic characteristics of models with additional devices are researched by adopting numerical simulation and taking a certain made-in-china truck model as research object. The mechanism and the effect of reduction of drag coefficient are analyzed and the optimization of model is gained based on contrast to the drag coefficient of base model. The results indicate that the drag coefficient descends in the most degree after roof fairing of cab is applied and the shape of roof fairing has a great influence on drag. The grille and separator can reduce drag coefficient. The research results can reduce the drag coefficients and provide the theoretical references for energy conservation and emission reduction of heavy-duty trucks
