Gamma Re_th transition model #8

Open sree-kanth opened 9 years ago

sree-kanth commented 9 years ago

Hi Andrealani,

Just had a look at the repository - congratulations on this amazing work!

Was just wondering if the Gamma Re_th transition model is fully implemented and if it can be used for compressible flows. I am interested in getting this working on a flat plate to start with and would be grateful if you can point me in the right direction.

I actually came across this report by A. Haas: https://www.vki.ac.be/download/dcsummaries/09-10/haas.pdf. Wasn't sure if the implementation files are still intact and if I could try and run it by myself, if possible, to compare against some experimental data that I have here. Will probably be a good validation for the code as well and would be happy to acknowledge the support. Thanks!

Warm regards, Sree.

Dear Sree, the model is indeed implemented and it was also used for producing some nice results on a supersonic 2D ramp (http://arc.aiaa.org/doi/abs/10.2514/6.2012-3151). I will ask the main author of the paper, Khalil Bensassi, to create a new regression testcase for that simulation to include in the official COOLFluiD distribution, so that you can then modify it to run what you need. Give us a few days and I'll get back to you. At the moment, I cannot guarantee that what you found on Haas' report is 100% usable. Many things have changed since the time he ran the code (5 years ago ). Best Andrea

Dear Andrea,

Many thanks for your response!

Very nice to know that the transition model is available and giving good results! It would be great if we can get a copy of the setup to try out ourselves. Shall look forward to hear back from you in that regard! Thanks again!

Warm regards, Sreekanth.

Hi Sree,

I implemented the Gamma Re_theta transition model fews years ago, and we are working on submitting the testcase that i have been using for validation. The details are given in a conference paper: AIAA 2012-3151. Please do not hesitate to contact me if you need more infos or details on the implementation.

Cheers,

Khalil

Hi Khalil,

Thanks for your response! I am planning to use this model in CoolFluid to compare the results with results from a commercial CFD code for hypersonic Mach numbers (mostly inter-code comparison kind of study) and further compare it with experimental data - for simple planar and axisymmetric geometries. I have got some results for flat plate cases using the commercial code to start with - would be great if you could let me know how I could setup a flat plate simulation and use this model in CoolFluid, so that I can try out a few simulations within the next week or so. Looking forward to hearing back from you soon!!

Thanks and warm regards, Sree.
