Heating sources localization based on inverse heat conduction problem resolution

In the context of parametric identification, the study presented in this communication is based on the implementation of an iterative regularization method (conjugate gradient algorithm) in order to identify coordinates of several heating fixed sources in a three dimensional geometry. Such an inverse heat conduction problem (described by a set of partial differential equations) is ill-posed (in Hadamard's sense). The robustness of the proposed identification method is illustrated considering temperature measurements (observations are performed using three sensors) and realistic disturbances.
