| Abstract: |
| For wind tunnels, it is essential to conduct temperature and flow field calibration on their test section, which is an important indicator for evaluating the quality of wind tunnel flow fields. In the paper, a truss composed of temperature sensors was used to calibrate the temperature field of a completed wind tunnel section. By adjusting the distance between the temperature measurement truss and the nozzle, as well as the wind speed, the temperature field distribution data at different positions could be obtained. Analyze these data to identify important factors that affect the distribution of temperature field. Simultaneously, the temperature field of the wind tunnel was simulated accordingly. The purpose is to further analyze the fluid heat transfer between air and wind tunnel walls through numerical simulation. Through the above analysis methods, the quality of the temperature field in the wind tunnel has been further verified, providing reference for future wind tunnel tests of relevant models. |

| 对于风洞来说，对其试验段进行温度和流场校准至关重要，这是评估风洞流场质量的重要指标。本文利用一个由温度传感器组成的桁架对一个完整风洞截面的温度场进行了测试。通过调整测温桁架与喷嘴之间的距离以及风速，可以获得不同位置的温度场分布数据。分析这些数据，以确定影响温度场分布的重要因素。同时，对风洞的温度场进行了相应的模拟。目的是通过数值模拟进一步分析空气和风洞壁之间的流体传热。通过以上分析方法，进一步验证了风洞内温度场的质量，为未来相关模型的风洞试验提供了参考。 |
