Abstract
Heat conduction is a well consolidated subject worldwide, however, a thorough knowledge about this phenomena is a matter of paramount importance for the development of several applications. In light of this, the study presented here shows a numerical solution for an unsteady heat conduction in a composite medium with a cylindrical heat source positioned in the first layer. A two-dimensional heat conduction problem was evaluated within an axisymmetric computational domain, which was discretized through the finite element method. As a source term, several values of constant internal heat generation were applied. Therefore, temperature profiles were investigated in radial and axial directions. Further, a pair of thermal insulation materials were added at the top and bottom of the heat source. Results indicated that an appropriate amount of insulation material must be placed in order to assure more heat propagating through the radial direction.
