The goal of this work is the numerical modelling of conjugate heat transfer in industrials furnaces, where the multi-domain problem (heat transfer in ingots and surrounding fluid) is treated by means of an Immersed Volume Method, which combines a Level-Set approach for representation of interfaces, mixing laws to represent effective physical properties and an anisotropic mesh adaptation process, leading to an accurate description of the interface. This approach has shown satisfactory results, but the numerical results don't fit the experimental data in situations where radiation is the dominant mode of heat transfer.
In this work, we present a computation model for numerical simulation of thermal radiation. Radiation is modelled by solving a set of two coupled partial differential equations, the so-called minimum entropy closure model, or M1 model. A Stabilized Finite Element Method (SFEM) is developed for this system, tested on some illustrative benchmarks and compared with the diffusion approximation in situations when this approximation is known to give irrelevant results
