Adomian Decomposition Sumudu Transform Method for Convective Fin with Temperature-Dependent Internal Heat Generation and Thermal Conductivity of Fractional Order Energy Balance Equation

Abstract

In this study, Adomian Decomposition Sumudu Transform Method (ADSTM) is used to solve the fractional order energy balance equation to find the temperature distribution and the fin efficiency in a longitudinal fin with temperature dependent internal heat generation and thermal conductivity. The concept behind the use of ADSTM is to derive a solution of the fractional order energy balance equation. Here, we studied the variation of temperature distribution with internal heat generation for different values of embedding parameters and compared the obtained results with the results obtained through Differential Transformation Method (Ghasemi et al. in Case Stud Therm Eng 4:1–8, 2014) as well as with numerical results to check the accuracy of the method.
