Resumo: Improved lumped parameter models are developed for the transient heat conduction of a wall subjected to combined convective and radiative cooling. The improved lumped models are obtained through two point Hermite approximations for integrals. It is shown by comparison with numerical solution of the original distributed parameter model that the higher order lumped model (H1;1=H0;0 approximation) yields significant improvement of average temperature prediction over the classical lumped model.
