Abstract
In this article, the Differential Transform Method (DTM) is used to perform thermal analysis of natural convective and radiative heat transfer in
moving porous fins of rectangular and exponential profiles. This study is performed using Darcy’s model to formulate the governing heat transfer
equations. The effects of porosity parameter, irregular profile and other thermo-physical parameters, such as Peclet number and the radiation
parameter are also analyzed. The results show that the fin rapidly dissipates heat to the surrounding temperature with an increase in the values of the
porosity parameter and the dimensionless time parameter. The results also show that the heat transfer rate in an exponential profile with negative
power factor is much higher than the rectangular profile.
