摘要
1前言高温风洞的温度高达1700℃,流速达0.9马赫数。为了测量风洞中气流温度分布的均匀性,通常采用铂铑30-铂铑10热电偶温度传感器,但是它只能采用逐点移测法,因此它不可能在同一时刻将一条检测线上气流温度测量出来。同时在高温气流测量时,热电偶接点由...
Thermo-video system typed TVS-2200 has been used to measure the temperature fieldof gas flow with high temperature and high speed generated in a high temperature windtunnel. The silicon carbon sheath of thermocouple sensor was considered as a referentialobject and its surface temperature was measured using a thermo-video system. Accordingthe convective heat transfer coefficient between the referential object and the gas flow, thereal temperature distribution of gas flow was calculated.
