MODELING A MIXING ELBOW (2-D) USING GAMBIT

In this tutorial, you will use GAMBIT to create the geometry for a mixing elbow and then generate a mesh. The mixing elbow configuration is encountered in piping systems in power plants and process industries. It is often important to predict the flow field and temperature field in the neighborhood of the mixing region in order to properly design the location of inlet pipes.
In this tutorial you will learn how to:
• Create vertices using a grid system
• Create arcs by selecting the center of curvature and the endpoints of the arc
• Create straight edges between vertices
• Split an arc using a vertex point
• Create faces from edges
• Specify the distribution of nodes on an edge
• Create structured meshes on faces
• Set boundary types
• Prepare the mesh to be read into FLUENT 4
• Export a mesh
Prerequisites
This tutorial assumes that you have worked through Tutorial 1 and you are consequently familiar with the GAMBIT interface.
