An inverse heat conduction problem in estimating thermal conductivity coefficient of refractory materials

The determination of the thermal conductivity coefficient of the refractory materials is studied based on the inverse heat conduction problem (IHCP) in this paper, the inverse heat conduction problem is solved by using conjugate gradient method (CGM), and then the influences of different measured temperature errors and initial guesses on inversion results are discussed. In the inverse process, the computed temperatures at measuring points were acquired by solving the direct heat conduction problem with the finite difference method. Numerical experiments show that the proposed method performs a higher precision and improves the resistance of inversion results for solving the determination of thermal conductivity coefficient which is called the inverse heat conduction problem, and finally the better satisfactory inversion results is obtained with the method. © Sila Science.
