Tutorial: 3D Simulation of the IFRF IndustrialPulverized-coal FurnacePu rposeThe purpose of this tutorial is to simulate a realistic industrial pulverized-coal furnace andcompare the results with the measured data.Prerequ isitesThis tutorial assumes that you are familiar with the FLUENT interface and have a goodunderstanding of the basic setup and solution procedures. Some steps will not be shownexplicitly.This tutorial uses the mixture fraction/PDF model with the k-epsilon turbulence modeland P-1 radiation model. If you have not used these models before, it would be helpful torefer to the FLUENT 6.2 Tutorial Guide.This is an advanced tutorial, and hence it is recommended that you refer to the 2D coalcombustion tutorial before you run this.Problem DescriptionThe International Flame Research Foundation (IFRF) experimental facility is an ideal sim-ulation to validate industrial coal combustion models. Comprehensive in-flame measure-ments of temperature, species, and velocities are made in an unstaged (thus high NOx),swirl-stabilized and pulverized coal flame.The tutorial is based on an extension of the 2-dimensional simulation of this furnace byPeters and Weber [1] to 3 dimensions. Boundary conditions and material properties, whereappropriate, are borrowed from this reference.One quarter periodic model is used, asillustrated in Figure 1.cFlu ent Inc.
