... calculations demands suitable numerical model. In the present work a three dimensional transient heat transfer model is developed for billet heating in reheat furnaces. Conduction heat transfer within the billets is modeled using Finite Difference Method (FDM). Fully implicit spatial discretization...

... equations governing heat and mass transport in a single brick (critical) are discretized by Finite difference method. The resulting PDEs together with temperature and humidity boundaries have been solved numerically. These equations are derived by combining conservation laws with Fourier’s law for heat...
