Main Article Content



In this paper, heat transfer characteristics of a straight fin having temperature-dependent thermal conductivity were computed by using three dimensional CFD analysis and MATLAB differential equation solver. The computations were performed with two different cases having both constant and linear function for thermal conductivity property. The CFD and MATLAB results were in good agreement with the data available in the literature. With the help of using these numerical techniques, fin efficiency can be improved and heat transfer rate of fins can be augmented by changing fin materials with variable thermal properties and air flow conditions. Application of the  proposed method can be effectively extended to solve the class of similar nonlinear fin problems in engineering and sciences.
