摘要：

To study the unsteady aerodynamics of a vehicle body, a large-eddy-simulation of a transient turbulent flow around a simplified vehicle model subjected to a sudden crosswind is conducted. A numerical boundary model is introduced to simulate the entry into the crosswind and it successfully represents the situation. The numerical results show unsteady aerodynamic forces, especially a transitional drag force, acting on the vehicle body when the vehicle is initially subjected to crosswind. Furthermore, on the basis of visualizations of the numerical results, the mechanisms generating the transitional forces are discussed. ©2010 Society of Automotive Engineers of Japan. Inc.
