Simultaneous Test Method of Force/Pressure in FullScale Automotive Wind Tunnel

Abstract:

In fullscale automotive wind tunnel with openjet test section, targeting notchback MIRA body, variation law and distribution rule of force/pressure test data error between simultaneously testing method and respectively testing method were revealed by wind tunnel test in a range of Reynolds number and yaw angle. The error was subsequently explained by computational fluid dynamics in view of flow mechanism. Finally, the specific implementation and application scope of force/pressure simultaneously testing method in fullscale automotive wind tunnel were concluded.
