摘要:

介绍了双通道恒温风洞检测系统的设计和性能。该系统的双通道恒温风洞有温度、风速稳定, 可控温差可调等优点,并且通过实验检验了风洞的性能,风洞内部定点温度脉动标准差(最大处0.025℃)比室内脉动(0.059℃)小,风洞内横向温度场不完全一致,有一定的温度分布,冷热风洞标准差分别为0.044℃、0.103℃。双通道恒温风洞检测系统主要是用于对QHTP-2温度脉动仪进行各种实验操作的平台,通过风洞系统实验验证了热源照射对温度脉动仪的测量会产生辐射增温的影响,在实验条件下的增温大小为0.365℃。

Abstract:

The design and performance of two-channel constant temperature wind tunnel detection system is introduced. The tunnels of system can make temperature and wind speed stable, and the differential temperature can be adjusted. The performance of the system is tested through experiments. The standard deviation of air temperature fluctuation of the fixed points in wind tunnel (0.025℃-the maximum) is smaller than which ( 0.059℃)in room. The transverse field of temperature in wind tunnel is not homogenous, which in cold and heating tunnel the standard deviations are 0.044℃ and 0.059℃. The system is used as a platform mainly for testing HTP-2 micro-thermal meter. It is proved that heat radiation has bad influence on measurement of micro-thermal meter by the system, and the radiative heating of the wire filament of micro-thermal meter is 0.365℃.
