Introduction

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.
