I have quite a bit of work to do with this but I will get to it eventually. I am just finishing a senior year project which is eating up massive amounts of my time. I also don't like any of the data/results I have other than the experimental. I have been considering posting the experimental data but I think it would be better to just have a single table comparing all of the results.

The one item that is really holding me back is the geometry. I tried to use graph paper and a vernier caliper to make my model but I found this difficult with quite the lack of accuracy and precision. Our institution will eventually have a CMM machine and between this machine and local machine shops I will eventually get at least a profile. A profile like this will allow me to create my model entirely within Salome without too much difficulty. The approximation (sketch of cross section) I used in my first analysis was a combination of an ellipse, straight lines, and several arcs produced using Catia. I would prefer to do everything with open source packages especially since software like Catia can be expensive to use in commercial applications.

When I did this project we used Gambit to create the mesh and used Fluent/OpenFOAM as solvers. I tried to solve using Code Saturne but I could not get the mesh in a format that program would accept. I used Fluent to post-process but I could not get the OpenFOAM results to import properly. Overall the project was a bit of a failure so I would like to try to do it all over again properly. My intentions were to use open source programs to create geometry and mesh but then solve using open source and commercial packages. Post processing would be done accordingly and the results compared. I did create a mesh and solve in Code Saturne but the meshes were extremely different. One problem with analyzing aerofoils is that we were interested in lift and drag which were not too easy to extract. That was one advantage to post processing OpenFOAM results with fluent which has built in functions to determine forces on walls.

I plan to take another CFD course next semester and my course load is much reduced so I hope to get this done quickly at that time (September 09).

I am postponing any attempt to redo the project I did comparing CFD and experimental lift and drag on an aerofoil. In the meantime I am planning to do some Fluent tutorials from Cornell with Salome/Saturne.
