Abstract
The solution for the energy transfer in a finned-tube radiator configuration is derived, considering the surface radiative heat transfer and internal heat conduction. The radiative interaction between adjacent radiator elements has been included, and thus a resulting non-linear integro-differential system of equations arises to describe the combined conduction-radiation heat transfer problem. This system is normalized and shown to be represented by two dimensionless radiative parameters. Convergence analyses for the integro-differential system for various combinations of the non- dimensional parameters are presented and compared based on the Generalized Integral Transform Technique (GITT). The numerical results indicate the effectiveness of the hybrid method for the proposed solution scheme and it is shown how the convergence behavior is directly affected by the dimensionless radiative parameters.
