| 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. |
