Abstract

Heat transfer is an integral part of most processes and machines, whether it’s cooling a machine or heating a solution. Naturally, heat flows from the highest temperature to the lowest. This driving force is defined as the temperature gradient. Heat will dissipate as it flows through the medium into the surrounding air. This study was conducted using an Extended Heat Transfer Unit. In this study, a brass rod was heated and the temperature profile observed. The experiment was simulated using COMSOL and this was compared to experimental data. The objective of this study was to compare the experimental results of an extended heat transfer pilot unit to the simulated results. The error between the simulation and the experimental results grew larger the higher the current output. There is no formal documented work on simulation of the extended heat transfer phenomenon, with an accurate simulation of extended heat transfer the model obtained could be implemented in more complex models such as fuel cells and furnaces.
