I can propose you something which is not new from research side, but can be very useful from ingeneering/user point of view.
Recently, I have encountered problem analyzing unconventional airfoils at low reynolds numbers of order 10^5. At such reynolds numbers one has huge problems with turbulence modelling, as flow is neither fully turbulent nor laminar: there are separation bubbles and transition to turbulence.
There is a good piece of software, called x-foil, which copes much more better with such analysis than any cfd-sofware, but it only works for conventional airfoils.
In my case I was analysing airfoils with backward facing step on the surface, so I had to use LES with gambit/fluent: I had an idea to write an authomatic software, say in mathlab or scilab, that generates journal files for gambit and fluent so that other non-ultra-specialist people could use them, but had no enough time to finish the project.
In more detail: you can write a program in matlab or scilab (better scilab since it is free), that takes airfoil (or multiple airfoil) coordinates, reynolds number and angle of attack/free stream turbulence intensity, and then generates gambit and fluent journal files for LES simulations.
If you write such a program and then post it somewhere, thousands of persons will be grateful to you, and still such a project looks like an excercise.
I could pass you scilab/journal gambit/fluent files I have stopped at.
