A new filtering approach dedicated to heat sources computation from thermal field measurements
Résumé
This paper presents a new approach in heat source evaluation from thermal field measurements. A modal projection based on dynamics (Discrete Modal Decomposition) is used to estimate the spatial term of a heat diffusion problem. A numerical example is presented in order to validate this approach and compare it to a more classical spectral decompostion (based on strictly thermal considerations). Results show that the proposed projection basis not only provides closer assessement of the heat sources but is also more stable to measurement noise and side effects.
