Yes, DG, discontinuous FE, whatever you want to call them. DG is pretty hot at the moment, would be a good choice for you. Don't know anybody in UK doing DG, though... Maybe not DG country... Any guys from the island know a DG group there?

Can you please clarify if you are intending to get a PhD from your institution in India and to visit European universities to gain CFD experience or if you intend to get a PhD in an area of CFD from a European university.

The problem I see is that you are in no position to propose a topic for a PhD study in the area of CFD because you are not an expert in CFD and nor is your supervisor. In order to address this problem efficiently you would seem to have no option but to talk to people who are experts in CFD. That is, people who propose CFD topics for funding by research councils and supervise PhD students. I am afraid that such people very rarely post on forums like this and so you will probably have to talk to them directly.

I have to agree again. You (thread starter) should have a rough idea what you would like to do, and then contact professors of your choice working in the field. Listen to what they can offer you, ask for advice, and then when your credentials can convince them, decide.
This should also ensure that yor project will be connected to the work focus of your fellow phd student colleagues, one of the most important boundary conditions for a successful completion of the phd!

DG-FEM in UK:

Suli @ Oxford, Houston @ Nottingham

Italy:

Antonietti @ Politecnico di Milano, Bassi @ Bergamo

Germany:
Ralf Hartmann @ DLR (not at uni anymore, but maybe he can supervise a Ph.D. student in collaboration with the University of Heidelberg or such).

I would also consider people doing work in the field of Uncertainty Quantification, expecially stochastic expansions. Quite hot in the US and getting hotter by the day in Europe.

Rebay in Brescia, Italy
Hillewaert at Cenaero, Belgium
Gassner in Stuttgart, Germany

There's also a guy (maritime fluid dynamics) in Spain, I think, but can't remember his name.. Porte-Agel maybe?

anyway, since the guy who started the thread hasn't posted back yet, I think we have answered his question....

Thanks for all your help.

I plan to contact some of the specialists you've mentioned here. I also intend to do a bibliographical research in high-order schemes (both spatial and temporal).

I plan to start my PhD with an article in which I will detail my spatial integration scheme. Since this scheme is applied on the invisicid flux I think I will limit myself for start to a parallel implementation of a Euler solver.

Do you guys think that a 4th order 2D Euler solver (parallelized on CUDA) with a new spatial integration scheme is a publishable subject ?

That again depends on your new scheme. I suggest you present a careful analysis of your scheme, especially its stability properties when coupled to standard time integrators, an analysis of the dispersion and dissipative behavior and efficiency considerations. Then, that should make a sound basis for a paper.

Out of curiosity: what's good about your new scheme? does it outperform others in certain areas?

Cheers

It has lower computational needs (less operations) than the scheme of Roe (which after my knowledge is one the most used flux difference scheme) and comparable accuracy.

[cfdnewbie]

Oh, maybe I misunderstood you... So it is not a novel spatial discretization scheme, but a novel Riemann solver?
Roe's Riemann solver is a very popular choice, I'm not aware of Roe scheme, but I am no FV person...
