摘要：

The flow quality of automotive wind tunnel test section can be improved by decreasing the axial static pressure coefficient. Both test results and numerical results show that the axial static pressure coefficient can be improved by increasing the collector angle or increasing gap of collector throat, and their effects become more and more obvious with larger collector angle and larger gap of collector throat. In addition, the influence of the axial static pressure by only increasing the collector angle or only increasing the gap of collector throat, and increasing both of them are compared. These findings can help to improve the axial static pressure of full scale automotive wind tunnel.
