| Abstract: | The influence rules of underbody diffuser on light-bus aerodynamic characteristics are studied with the method of numerical simulation.The 1:5 simplified model of light-bus with different underbody diffuser angle is simulated.Through the analysis of aerodynamic drag and lift,the influence rules of underbody diffuser on light-bus aerodynamic characteristics are achieved.The conclusions of calculation of analysis provide the theoretical foundation for styling optimization of light bus,which are very helpful to decrease aerodynamic drag,optimize styling and develop new vehicle styling. |
