Abstract:This paper presents a general numerical model to identify multi-variables of two-order transient heat conduction problems and the homotopic method is employed to solve inverse problems based on Bregman D-Function. A time stepping scheme is used for transient analysis and the finite element model is given, facilitating to sensitivity analysis for direct and inverse problems. Combined identifications can be carried out for thermal parameters and boundary conditions etc. Satisfactory numerical validation is given including a preliminary investigation of effect of noise data and initial value on the results.
