Entropy generation rate is directly related to exergy destruction and is therefore to useful energy. This study investigates temperature distribution and local and total entropy generation rates within a composite hollow cylinder with temperature-dependent thermal conductivity and internal heat...

This article investigates the classical entropy generation in cooled slabs. Two types of materials are assumed for the slab: homogeneous material and FGM (functionally graded material). For the homogeneous material, the thermal conductivity is assumed to be a linear function of temperature,...

Like dry surface fins, development of the boundary layer over a wet fin causes the heat transfer coefficient to vary over the fin surface. The present study analytically determines the performance of different fins geometries by analyzing the temperature-dependent thermal conductivity of the fin...

In this paper, the homotopy analysis method (HAM) has been used to evaluate the efficiency of straight fins with temperature-dependent thermal conductivity and to determine the temperature distribution within the fin. The fin efficieny of the straight fins with temperature-dependent thermal...
