Determing the flowfield on a swept wing

[RandomGuy88]

Hello,

I am looking for software that I can use to computationally determining the flowfield over a 3D swept wing. Perhaps using a vortex lattice method. I have very little experience with any kind of aerodynamic computational modeling.

Is what I really need to do is be able to put my wing geometry in the program to determine the baseline flowfield characteristics such as the velocity distribution including the spanwise velocity component. Then I will need to remove a section of the wing and and determine how the flow field has changed. For example I would remove perhaps from midspan to the tip and determine the flowfield over the portion of the wing that remains. If possible I would also need to model wind tunnel walls and the effects they have on my model.

Does anyone know of any programs that are capable of this. Like I said I have very little experience with this sort of thing.

Thanks for your help.

What you're looking for is a computational fluid dynamics (CFD) program. There are some free codes/programs out there that might fit your needs, but I have no experience with any of the free ones.

http://en.wikipedia.org/wiki/X-Plane_(simulator)" isn't a CFD, per se', but it does include both an aircraft designer and employs CFD techniques, real-time, via its blade element theory engine.

I don't know if it'll model spanwise flow, but it might. It's certainly good enough for FAA certification as a simulator, and people have designed aircraft using it. It may be worth a try.
