Analytical bounds and finite element modeling of the temperature distribution on a thin plate heated by a localized radiant source
Keywords: radiative heat transfer, finite element method, Newton linearization, Stefan-Boltzmann law, method of manufactured solutions, a priori bounds
This work investigates the steady-state temperature field induced on a thin plate by a small high-temperature radiative source placed at a finite distance. A nonlinear source-to-surface model is derived by coupling...
Analytical and numerical methodology for the temperature distribution on surfaces exposed to a radiant heat source
Rio de Janeiro, Brazil
Keywords: Thermal radiation, Heat conduction, Nonlinear heat transfer, Finite element method, View factor
In this work, we investigate the effect of a small, high-temperature radiant source on a surface located at a significant distance. Starting from a partial differential equation with Neumann boundary conditions, we...
On the Temperature Distribution in a Flat Plate Induced by an External Thermal Radiant Source
Vitoria, Brazil
Keywords: Nonlinear heat transfer, Thermal radiation, Finite element method, Newton’s method, Variational formulation
This work presents a comprehensive numerical and analytical analysis of steady-state temperature distribution in flat plates subjected to external thermal radiation sources. The mathematical model incorporates nonlinear...
A Robust Newton-Based Variational Framework for Nonlinear Conduction-Radiation PDEs with Localized Sources
Montes Claros, Brazil
Keywords: Nonlinear PDEs, Newton’s method, variational formulation, finite element method, fourth-power nonlinearity
A steady radiative-conductive problem is considered in a thin rectangular plate irradiated by a small hot source positioned at height H. A standard thickness reduction leads from the 3D balance equation to a 2D nonlinear...
