Dear freinds

I don't have any background in POD (or ROM), but have interest to it. If you have experience, please guide me how enter in this field. (Introduce some basic refrences, easy to understand).

Also, How is implementation of POD ? (suppose the CFD code is present)

The earliest work was by Sirovich. Also look for work by Lumley and Holmes at Princeton and Dowell,Hall and Thomas at Duke and Beran at AFRL. The latter two reference groups are involved in aeroelastic computations.

If you have a CFD code the way you implement it is to basically run the CFD to obtain data to get your POD modes. Then once you have the POD modes you project the modes onto your governing equations(Galerkin or subspace projection).

Hi:

Peter Attar, what do you thinke of the future of the POD, my supervisor want the POD be my doctor's subjects, but i think it is a old technique, so what is your idea!

I think it has it's place. Right now computers are still not fast enough to allow optimization with 5 million grid point CFD models so a medium fidelity(between panel codes and full blow CFD) method like POD is perfect. Are you planning on doing a purely CFD thesis or some aeroelastic/fluid-structure interaction problems? What type of POD work is he proposing for you?

I don't have any of them electronically..and I don't have time to search for them download them and then send them to you...sorry. If you are at a University just go to your library and search in one of the libraries techical search engines..Compendex for example.

As I mentioned to the previous poster I do not have these electronically..do a literature search and I 'm sure you can get them all yourself.
