Numerical Simulation of the Influence of Curvature Radius on Aerodynamic Characteristics of the Moving Vehicle

Abstract:

Based on moving grid and dynamic boundary conditions, the transient aerodynamic characteristics of the flow field around vehicle were studied when simplified model was driving in the crooked road. The influence of curvature radius on aerodynamic characteristics was studied through the analysis of the drag coefficient, the side drag coefficient and the changes of the flow field. The conclusions provide theoretical reference for the further study of the transient aerodynamic characteristics of turning vehicle.
