“…The inverse heat conduction problem (IHCP) involves the determination of the heat flux at the surface of a solid using one or more measured internal temperature histories. A number of methods have been proposed including function specification [1,2], Tikhonov regularization (TR) [1,3,4,5], conjugate gradient (CG) [6,7,8,9,10] and singular value decomposition (SVD) methods [11,12,13,14]. The problem is challenging because it is ill-posed which is, in part, caused by the internal measurements being delayed and damped compared to the heated surface.…”
