RESOLUTION OF INVERSE HEAT CONDUCTION PROBLEM WITH REDUCED MODELS
摘要
For linear heat conduction systems, we propose here to solve
an Inverse Heat Conduction Problem (lHCP) that consists in the identification of several time varying thermal solicitations from measured temperatures.
Usually, for a complex system, the numerical modelling of the transient diffusion equation leads to a vector differential equation of large size. Instead of using such a model for the IHCP which is ill-posed, we propose at first the transformation of the original modelling called Detailed Model into a Reduced Model. This last one, built with the dominant eigenmodes, filters the high frequencies and then acts as a regularization procedure.
