Abstract

The overlapping grid method is a novel region segmentation and grid combination strategy. Based on this method, the aerodynamic characteristics of lineup vehicles in meeting conditions are simulated in this paper. Firstly, the data obtained from the single-vehicle simulation is compared with the wind tunnel test data, and the error value is relatively small, which verifies the validity of the overlapping grid method. After that, simulation was carried out to analyze the changes of flow field around the cars in formation, and the differences between the front and rear cars in formation were summarized. Finally, the vehicle pressure field, velocity field, aerodynamic coefficient and torque coefficient were statistically analyzed, and the influence of the car meeting on the aerodynamic characteristics of the queue was studied.
