Thermal Parameter Estimation of Sandwich Panel using Numerical Solution of Inverse Heat Conduction Problem

Resumo

In this work, a numerical formulation to solution of the inverse heat transfer problem, based in the implicit finite difference method and Monte Carlo method, is developed to estimate the thermal properties of the sandwich panel. It is realized the sensitivity analysis of the parameters and the thermal contact resistance along the layers interface is used. Experimental results of temperature are used in the numerical formulation to determine the thermal properties (conductivity and the specific heat) of the layers materials and to predict the thermal behavior of the panel. The results obtained show that the formulation estimates with adequate accuracy the material thermal proprieties.
