Summary

The scaled boundary finite element method is a semi analytical fundamental solution-less boundary-element method which links to both finite elements and boundary elements. In this paper coupling of scaled boundary finite element method (SBFEM) and genetic algorithm (GA) is used to solve inverse heat conduction problems (IHCP) for a square plate in a two dimensional steady state. Inverse heat conduction methods can be used to determine heat flux and temperatures on an inaccessible surface of a wall by measuring the temperature on an accessible boundary. Herein, the unknown heat flux at the boundary is estimated using an IHCP. Temperature differences between the calculated and exact values at the middle of the plate is considered as the objective function. The validation of the SBFEM results is proved by comparing temperature distributions which are determined using the finite element method. The accuracy of the SBFEM and the low computational cost demonstrates an efficient method for IHCPs.
