simulation of an EARSM model over flat plates and compressor blade (OpenFOAM)

Hello,
I am a student and my task is to run simulations over three flat plates (t3a, t3b, t3am) and a compressor blade cascade (V103A with NACA 65 profile) with a self-customized EARSM model coupled with an algebraic transition model. (The EARSM model will also have a laminar-to-turbulent transition model added in it). I have already done 90% of the task: geometry, code, boundary conditions, simulation, and post-processing for the flat-plates. But, I think the remaining 10% of work will take other millennia to finish if I keep working by myself. I will need relatively more help in simulating compressor blade cascade. Now, there are some errors in them and I am looking for some expert's advice for removing those errors. I am running out of time so I am in a little hurry. I am attaching a few graphs which are results of what I have done till now. 1, 2. turbulent intensity decay graph and friction coefficient graph for t3a case. 3, 4. for t3b case..... I'll update later 5, 6. for t3am case.......I'll update later 7, 8, 9, 10. for two sides of the compressor blade... I'll add here later. Thank you, please mail me on 786purn at gmail dot com 786purn@gmail.com Images should be visible below but they are not. :| So posting their URL again: 1: https://drive.google.com/open?id=1rj...8l2H3DSEHnG0Z3 2: https://drive.google.com/open?id=1z9...XeGh19q0PXMnAN Last edited by purnp2; September 25, 2019 at 06:10.

https://drive.google.com/open?id=1VIowq9VVDj3m8s1fbwP3NQHfu_RRKhnu Hello, sir. I have to couple an EARSM model (with an extra anisotropic term ( a_ij ) in Reynolds Stress Tensor) with an algebraic transition model (Kubacki-Dick model). I have already prepared the code. See the .C and .H file of the model named EARSM_Trans_kd attached in the mail. Using this model I have to prove the usefulness of the extra anisotropic term ( a_ij ) used in the EARSM model by comparing the result of this model with the result of another model which doesn't have this anisotropic term in it. I'll be running the above two different models on three flat plates (t3a, t3b, t3a minus) and a compressor blade cascade ( v103A with NACA 65 profile). I have already run the cases on all the flat plates but I'll run the cases on compressor blade cascade within this week. Please check the turbulent intensity decay graph and friction coefficient graph for the first flat plate ( t3a ) case:: compare_Turb_Int.png and compare_C_f_.png. I am using the first model described in the attached publication "Holman_Furst_Model_2019_Art......" and the second model published in the file "thesis_Tykocki.pdf". All the files are in the Google Drive link I have attached on the top. This is the birds-eye-view of what I am doing. I think still it is hard to completely understand what I am doing. After you look at these sources then we can contact on skype and do video chat where I can screen-share with you and explain what I have already done and where I'll need your help. Please text me in the inbox for sharing the contact of skype/messenger/Duo. Regards Purn |
