Modeling natural convection and radiation, Ansys Fluent Tutorial 13

In this tutorial, combined radiation and natural convection are solved in a three-dimensional square box on a mesh consisting of hexahedral elements. This tutorial demonstrates how to do the following: • Use the surface-to-surface (S2S) radiation model in ANSYS Fluent. • Set the boundary conditions for a heat transfer problem involving natural convection and radiation. • Calculate a solution using the pressure-based solver. • Display velocity vectors and contours of wall temperature, surface cluster ID, and radiation heat flux.
