Default High Lift Devices

I am currently working on the improvement of high lift device, a single slotted flap, for a light aircraft.

In this regard I intend to use CFD. I was looking for

a. Information on grid generation parameters b. Some sample problems if possible which can be solved using Fluent or other commercial codes c. Some references where CFD has been used for such a task.

Also I dont have specialized codes such as MSES and would like to know about the competency of various commercial codes in performing the above task.

I look forward to your help and suggestions and would be willing to share my experiences when I finish this work

with regards

Anshul

Almost seems like you are you looking for someone to do your work?

You seem to understand that there is a fair amount of survey work necessary before you delve into the application of CFD. It's not clear from your question if you actually have decided on a particular problem.

"Improvement of a high-lift device" could mean anything and nothing. You are surely seeking to maximize the lift to drag ratio in some way. Transition control? Separation control? Shape optimization? All this and much more has been addressed before and you can find a lot of information in fluid dynamics journals and textbooks. You might start with google.

"AIAA Journal of Aircraft, Vol.41, No. 4, pp.940-944, 2004." might help you.

Cheers.

Thanks for your reply.

I am looking at the shape optimization of an existing flap system. I have formulated my problem in terms of the design goals and the parameters that influence the behaviour of high lift devices (mainly from journal papers and NACA reports)and have some preliminary designs. As we cannot test my designs in a wind tunnel, we thought of resorting to CFD for optimization of the design and just validate the final design results in a tunnel.

From this post of mine I was looking at "Best Practices" for CFD for shape optimization of a flap system.

All I am looking at is how to go about the grid generation (because thats sort of a dark area for me as of now). So any help/test case or tutorial would be heartily welcome (NO Chimera grids please)

I hope I have made myself more clear now.

regards

Anshul

Dear Shivram,

What doubts do you have in high lift devices. If you could be more elaborate may be someone could help. I am giving a brief idea, mainly the literature I have referred.

For a basic understanding of the different types of high lift devices employed on aircraft, read Torenbeek.

I am currently working on slotted flaps. You can go through NACA reports 633, 664, 938 for this . These reports give wind tunnel data and discussion on various kinds of flap systems. These reports are available on the net and can be easily downloaded. Also search for NACA reports for specific kind of flap systems.

About optimization of flap systems using CFD I have referred work of Prof Zingg (Univ Toronto). His group has designed a slotted flap for Found Aircraft, Canada.
