Effect of Moving Belts and Tangential Blowing on Aerodynamic Force

Abstract:

Both numerical simulation method and wind tunnel test were used to measure the aerodynamic force of a sedan. Then, experiment results were corrected by the existing correction method. Comparison results show that the aerodynamic force obtained by the numerical calculation method has good consistency with the test results. Moreover, the study on moving belt form and tangential blowing angle indicates that different moving belts have little effect on the measured value of the aerodynamic force, and the difference of drag coefficient is less than 0.002; the tangential blowing angle also has little effect on the aerodynamic force.
