回流式低速风洞流场品质的测试及分析

Testing and Analysis of the Flow Quality of the Low Speed Closed Circuit Wind Tunnel

针对上海电力学院新建的回流式低速风洞,介绍了该风洞的流场品质的校测方法,并对测试数据进行了分析,主要包括风速范围、动压稳定性、动压场系数、局部气流偏角、紊流度及噪声6种数据.测试结果说明,该风洞流场品质满足工程研究的要求.

The testing method and data analysis of the flow quality of the wind tunnel, as a new low speed closed circuit wind tunnel in Shanghai University of Electric Power are presented. The testing contents include such six kinds of data as the range of wind speed, kinetic pressure stability, kinetic pressure field coefficient, local flow angularity, tubulence level and noise in the test section. The results show that the flow quality of this wind tunnel may meet the requirements of the structural wind tunnel test.
