高温高速气体的温度测量,由于环境的相互热辐射;传感器支座的相互热传导;气体的功能不能完全恢复(即使在稳定条件下,热接点的温度也与气体的实际温度不同),因此,建立热电偶校准风洞是十分必要的。我们曾为某工厂设计过一台热电偶校准风洞,为了和兄弟单位交流经验,现将设计中考虑的几个问题作一介绍。一、总体布局总体布局取决于加温器的好坏,加温器设
Temperature measurement of high-temperature and high-speed gases, due to the mutual thermal radiation of the environment, mutual thermal conduction of the sensor supports, and incomplete recovery of the gas function (even under steady conditions, the temperature of the hot junction is different from the actual temperature of the gas) Thermocouple calibration wind tunnel is very necessary. We have designed a thermocouple calibration wind tunnel for a factory. In order to exchange experiences with our brothers, we will introduce a few issues to consider in the design. First, the overall layout of the overall layout depends on the quality of warmer, warmer set
