Abstract

In the paper the inverse problem consisting in the identification of external heat source influencing the skin surface is presented. On the basis of the knowledge of heating curves at selected points from the domain considered the time dependent value of boundary heat flux is identified. In order to solve the problem the sequential function specification method [1, 2] and the whole-domain estimation of heat flux [2] have been used. In the stage of numerical computations the boundary element method has been applied. From the practical point of view the algorithm presented can be applied for the burns prediction.
