Numerical Research on Aerodynamic Characteristics of Lane-Changed Overtaking Cars Based on Overlapping Grid

Abstract:

Based on overlapping grid, two cars were simulated numerically through computer when lane-changed overtaking and the aerodynamic characteristics of two cars were achieved. By analysis the coefficients of side force and yawing moment and the flow field around two cars when two cars’ position changed the flow motivation and rules of interference each other were researched. The conclusions can provide the theoretical foundation for the research of transient overtaking
