Abstract: This study presents a method to solve a 3D inverse heat conduction problem in real time. The aim is to identify sequentially the time varying strength of two independent heat sources from non intrusive noisy temperatures measured by an infrared camera. Due to the geometry and the boundary conditions of the experimental setup, the modelling of the system leads to a high dimensional nonlinear model. The size of this detailed model forbids to solve the inverse problem. A reduced model is then built using the branch eigenmodes technique. This study shows that the identification of the heat sources strengths is possible using a very low order reduced model. Moreover, the computation times are very small, allowing the sequential identification in real time.
