Identification of Plate Surface Geometry: A Numerical and Experimental Study

Abstract

At present, most boundary geometry identification problems are solved by optimization methods. Due to the update of the boundary geometry in the method, the computational domain is changed and remeshing of grids is needed for each step of iteration, which will obviously increase the complexity of the computation process and prolong the calculation time needed. In this article, an indirect method is presented, in order to simplify the computational process, by transforming the identification problem of boundary-geometry into one of effective thermal conductivity. Numerical and experimental test cases have proved the effectiveness of the method.
