Time-dependent heat flux identification: Application to a three-dimensional inverse heat conduction problem

In the context of parametric identification, the present study deals with the resolution of three-dimensional inverse heat conduction problems for time-dependent heat flux identification (for both fixed or mobile heating sources). Considering such ill-posedness problems, an iterative regularization method based on conjugate gradient algorithm has been successfully implemented. Robustness of the proposed approach is investigated considering noise-disturbed measurements. It is shown that if the heating mobile source trajectory is known, time-dependent flux is accurately identified.
