Temperature measurement correction method for high-temperature solid wall surface

The invention provides a temperature measurement correction method for a high-temperature solid wall surface, and the temperature measurement result of the wall surface has a large error under the scouring of high-speed, high-temperature and high-pressure fluid. The method comprises the following steps: firstly, establishing a convective heat transfer equation between a temperature sensor and the fluid at one side of the measured wall surface, a radiation heat transfer equation between the temperature sensor and the surrounding environment, and a heat conduction equation between the temperature sensor and a lead; then calculating interference heat flux density according to a heat balance equation, establishing a cylindrical coordinate system by taking the sensor and the center of the measured wall surface as original points, establishing a heat conduction differential equation of the measured solid wall, and deducing a temperature correction formula of the measured high-temperature solid wall surface; and sub
