A Numerical Well-Balanced Scheme for One-Dimensional Heat Transfer in Longitudinal Triangular Fins

الملخص EN

The temperature profile for fins with temperature-dependent thermal conductivity and heat transfer coefficients will be considered.

Assuming such forms for these coefficients leads to a highly nonlinear partial differential equation (PDE) which cannot easily be solved analytically.

We establish a numerical balance rule which can assist in getting a well-balanced numerical scheme.

When coupled with the zero-flux condition, this scheme can be used to solve this nonlinear partial differential equation (PDE) modelling the temperature distribution in a one-dimensional longitudinal triangular fin without requiring any additional assumptions or simplifications of the fin profile.
