Abstract

Based on sapphire optical fiber blackbody cavity temperature sensor

an extrapolation measuring method for transient high-temperature was presented.The mathematical model was established and solved by separation of variables.On this basis

by CO2 laser simulating the transient high-temperature heat source

the sensors and high-speed infrared thermometer were simultaneously used to measure the temperature change inside and outside the black body cavity film.The experimental results show that the extrapolation temperatures obtained by separation of variables are consistent with the temperatures detected by infrared thermometer in the change trendency and the peak value aspects

which proves the correctness of the extrapolation model.At the same time

Ansys software is used to simulate the transient heat transfer process of the blackbody cavity heated

which proves the correctness of extrapolation model in the opposite direction.
