摘　　要：采用数值仿真的手段对燃烧室试验环境下单屏式多点气流温度传感器进行仿真计算,改变温场、流场环境,分析研究了来流总温、来流总压以及马赫数等工况参数对单屏式多点气流温度传感器的测量结果的影响规律,并用试验进行验证。数值模拟结果表明:在燃烧室试验环境下,单屏式多点气流温度传感器的测温偏差随着来流总温的增大而增大,每增加1000 K,测温偏差增大约2 K;随着来流总压的增大而减小,每增加100 kPa,测温偏差减小1 K左右;随着来流马赫数的增大而减小,马赫数每增加0.1,测温偏差减小0.7 K。以上结论可为燃烧室试验中气流温度参数的现场校准提供参考依据。By means of numerical simulation,the single screen multi-point air flow temperature sensor in the combustion chamber test environment is simulated,the temperature field and flow field environment are changed,and the influence laws of different working conditions parameters such as total inlet temperature,total inlet pressure and Mach number on the measurement results of the single screen multi-point air flow temperature sensor are analyzed and verified by experiments.The numerical simulation results show that under the combustion chamber test environment,the temperature measurement deviation of the single screen multi-point air flow temperature sensor increases with the increase of the total incoming flow temperature.For each increase of 1000 K,the temperature measurement deviation increases by about 2 K;with the increase of the total incoming pressure,the temperature measurement deviation decreases by about 1 K for every 100 kPa increase;it decreases with the increase of incoming Mach number,for each increase of 0.1,the temperature measurement deviation decreases by 0.7 K.The above conclusions provide a reference for the field calibration of gas flow temperature parameters in combustion chamber test.
