Abstract
The transient temperature distribution through a convective-radiative moving rod with temperature-dependent internal heat generation and non-linearly varying temperature-dependent thermal conductivity is elaborated in this investigation. Symmetries are intrinsic and fundamental features of the differential equations of mathematical physics. The governing energy equation subjected to corresponding initial and boundary conditions is non-dimensionalized into a non-linear partial differential equation (PDE) with the assistance of relevant non-dimensional terms. Then the resultant non-dimensionalized PDE is solved analytically using the two-dimensional differential transform method (2D DTM) and multivariate Pade approximant. The consequential impact of non-dimensional parameters such as heat generation, radiative, temperature ratio, and conductive parameters on dimensionless transient temperature profiles has been scrutinized through graphical elucidation. Furthermore, these graphs indicate the deviations in transient thermal profile for both finite difference method (FDM) and 2D DTM-multivariate Pade approximant by considering the forced convective and nucleate boiling heat transfer mode. The results reveal that the transient temperature profile of the moving rod upsurges with the change in time, and it improves for heat generation parameter. It enriches for the rise in the magnitude of Peclet number but drops significantly for greater values of the convective-radiative and convective-conductive parameters.

Summary
The heat transfer process has become one of the important topics in the research domain. Turut et al [27] used DTM along with multivariate Pade approximate to solve the PDEs. The steady-state heat transfer through a moving material using an analytical and numerical technique incorporating linear thermal conductivity is addressed in the aforementioned research works. To the best of the author’s knowledge, transient heat transfer within a moving rod involving internal heat generation using non-linearly varying temperature-dependent thermal conductivity is not yet investigated. The transient thermal distribution through a moving rod by considering temperature-dependent internal heat generation, heat transfer coefficient, and non-linear temperature-dependent thermal conductivity is scrutinized in the present investigation.
