Radiative energy transfer is important in high temperature simulations that include gases and surfaces that emit, absorb, and scatter radiative energy. In this workshop we will discuss the P1 Spherical Harmonics Method and the Discrete Ordinates Finite Volume Method, the different radiation submodels, and how to model radiative energy transfer in CONVERGE simulations. We will set up example cases that have thermal radiation in flows with and without combustion. PREREQUISITES Introduction to CONVERGE (or equivalent introductory CONVERGE training course)
