CE 496 Homework Assignment
Date: February 12, 2002
Due: February 19, 2002
This assignment asks you to extend the work you did on exercise 4.  Modeling a Combustion Chamber (3-D).  In all cases set Fluent 5.0 as the solver.

1.	Rather than a cylinder in the first step create a cylindrical frustum height H=12, R1=2, R3=4
2.	Continue with other construction steps including subtracting this frustum from a larger cylinder and adding the box for the burner.
3.	Rather than blending a round chamfer on two edges of the burner box, add a constant chamfer to the front two and top edges.  Set corner vertex first and then for edges use ranges left and right of 5.
4.	Split volume three ways to create triangular prisms along edges and a corner tetrahedron  (Hint in Gambit 1.3 use two points to sweep in each direction.  In Gambit 2.0 use a vector long enough to reach beyond end of combustion chamber).
5.	Continue with various meshing steps as before.…use hex cells, coopering, etc. as appropriate.
6.	Examine mesh….can you do anything to improve mesh beyond that shown below?  (What if you split volume with faces into sub volumes?)
7.	Create a .tif file that shows your final result, and a .msh file to document your work.

Place the .tif file and the .msh files you created in a folder titled “your_name_Set4” and drop this folder into >t:\classes\ce\ce496\drop-box.  (Note you will not be able to see into folder, but I should be able to access your folder.
