The aircraft wind speed tube is a crucial device for measuring flight speed and altitude.Surface Thermometer ManufacturerResearch on anti-icing has significant practical value.Surface Thermocouple ManufacturerThe calculation of the surface temperature of wind tunnels under icing conditions is a crucial aspect of their anti-icing research. The author, under a given heating power, calculated the surface temperature of the wind tunnel using a combined method of computational fluid dynamics (CFD) and heat transfer. By calculating the air flow field, the trajectory of supercooled water droplets, and solving the energy equation, surface temperatures of the wind tunnel under various conditions were obtained. The conclusions drawn from the calculated results are: under the given heating power, the surface temperature is above the dew point temperature, eliminating the risk of icing. The surface temperature field after heating exhibits significant changes at geometric variations. When the flight altitude and atmospheric temperature are constant, the surface temperature increases with the increase in flight speed. The atmospheric temperature has a significant impact on the surface temperature of the wind tunnel.
