TEMPERATURE DISTRIBUTION OF A TEST SPECIMEN WITH HIGH-SPEED HEAT AIR-FLOW PASSING THROUGH

ABSTRACT
In this paper, a solution method for the temperature distribution of rectangular test specimen with a high-speed heat airflow passing through is proposed based on the heat transfer theory and numerical calculation, and the feasibility of temperature prediction method is validated. Firstly, the partial differential equations (PDEs) to describe the average temperature in the section of the hot airflow and the specimen are established and the solving method using MATLsolver is proposed. Then, based on heat transfer conduction equation and the average temperature, the temperature distribution at the different point in each section is calculated. The comparison between numerical computation and experiment shows that two results are in good agreement, which verifies the correctness of the presented prediction method of the temperature distribution of the specimen.
