Iterative Solutions for the Nonlinear Heat Transfer Equation of a Convective-Radiative Annular Fin with Power Law Temperature-Dependent Thermal Properties

The temperature distribution in a conductive-radiative rectangular profiled annular fin with internal heat generation is scrutinized the present investigation. nonlinear variation of thermal conductivity and transfer coefficient governed by power law considered. analytical approximation for non-dimensional profile obtained using differential transform method (DTM)-Pade approximant. nondimensionalization governing energy equation dimensionless terms yields ordinary (ODE) corresponding boundary conditions. resulting ODE analytically solved assistance DTM-Pade approximant procedure. Furthermore, impact parameters on field stress elaborated graphs. important results report divulge that greatly enhances an augmentation parameter, but it gradually reduces increment magnitude thermogeometric radiative-conductive parameter.
