LOCATION AND IDENTIFICATION OF A VOLUMETRIC HEAT SOURCE IN A 2D DIFFUSION SYSTEM USING THE BOUNDARY ELEMENT METHOD
要約
In this paper a numerical study to determine a volumetric heat source, homogeneous in a part of the domain is presented. We demonstrate how a point heat source "equivalent" can approach the phenomenon at first. An extension of this point heat source is proposed. The method is based on a convolution integral inversion technique and on a direct model of the Boundary Element Method. The results obtained are in conformity with the simulation. Thus the location of the source centre is positioned in a precise way. On the other hand the power is estimated at 95% of error but two methods (increase from a circular source and method of the three point sources) are used in order to improve quality of the result. Also one manages to reproduce faithfully the temperatures pace.
