[ICEM] Structured mesh of a complete Dornier 228 with its propellers

Joachim · May 3, 2012, 10:56

Hello Everyone!

For my Master's thesis, I am currently trying to mesh a complete aircraft (Dornier 228) with its two propellers. I already have the CAD file, adapted for ICEM CFD (proper model, with curves, points,...).

The final goal of my thesis is to study the boundary layer at a specific location on the side of the aircraft. For this reason, I would like to build a structured, or at least hybrid mesh to properly capture this boundary layer.

My problem is: I don't have a lot of experience in CFD, and even if I have done all the ICEM tutorials, none of them deals with such a complex configuration. I have tried to create a blocking structure on my case, but it is causing me some troubles!

If you could recommend me a tutorial (I haven't found any), a book on the subject, or any advice, it would be extremely nice from you!

I can always do a fully unstructured mesh, with a prism layer at the wall and some density regions, but I would really like to know how to create a structured mesh!

Thank you very much for your help!

Joachim

You can download the blocking for similar cases from DAPW

If you plan to model the propellers, you should probably put the discs in early so you account for them in your blocking...

Thank you for the links and advice!

By the way, these files were made (probably) by Simon

I would be interested to see the final blocking for this case

Right now I am in my 3rd Year Of Bachelors, and has been assigned to design and conduct analysis on dornier do 228. I have designed the fuselage and the wing but I am not able to design its tail wing and the propellers in catia . Can you please suggest the ways to make the elevator,rudder and propeller in catia

I also wanted to know about the different kinds of tests which can be conducted in ansys on the entire aircraft body??

Hello again

The links above are not working for me.

Can anyone kindly provide me with some good links on meshing a propeller (steady mesh)?
