TL;DR: In this paper, a fully predictive, algebraic method has been developed for the prediction of the timewise temperature variation of a thermal load situated in an electrically heated oven, taking into account both natural convection within the oven cavity and radiation between the thermal load and the oven walls.

Abstract: A detailed numerical study of heat transfer to a fluid passing through a saturated porous medium is the subject of this study. The Green's function solution method is selected in order to accomplish this task. The interesting features of this methodology are the focus of this article. As a test case, primary consideration is given to the computation of heat transfer to a fluid flowing through a circular passage with impermeable walls filled with porous materials. The analysis includes the heating/cooling effects due to a temperature change at the wall of the passage. In addition, the contributions of frictional heating are examined.

TL;DR: In this article, the process of radiative heating of a moving polymeric sheet has been solved by numerical simulation, where the heating was accomplished as the moving sheet was stretched over a hot roll having a corrugated surface.
Abstract: The process of radiative heating of a moving polymeric sheet has been solved by numerical simulation. The heating was accomplished as the moving sheet was stretched over a hot roll having a corrugated surface. Radiative and convective heat losses were taken into account in the simulation. The heating process was subdivided into two time periods. The first of these periods occurred as the moving sheet approached the heated roll prior to making contact with it. During the second period, the moving sheet was in contact with the tips of the corrugations of the roll surface. The analysis of the problem led to a system of integro-differential equations. These equations were solved numerically to determine the timewise temperature variation of the moving sheet. It was found that the heating of the sheet prior to its contact with the roll surface is negligible. As the sheet passed over the roll, a transient heating period ensued which ultimately gave rise to a steady-state temperature of the sheet. For all of the...
