摘要: The heat transfer coefficient in a multidimensional heat conduction problem is obtained from the solution of the inverse heat conduction problem based on the thermographic temperature measurement.The modified one-dimensional correction method(MODCM),along with the finite volume method,is employed for both two-and three-dimensional inverse problems.Aseries of numerical experiments are conducted in order to verify the effectiveness of the method.In addition,the effect of the temperature measurement error,the ending criterion of the iteration,etc.on the result of the inverse problem is investigated.It is proved that the method is a simple,stable and accurate one that can solve successfully the inverse heat conduction problem.
