create new Reynolds Stress Model (RSM)
Hello,
I'm beginner in OpenFOAM and want to create new Reynolds Stress Model (RSM). That's Hanjalic and Launder model.(1998, CONTRIBUTION TOWARDS THE SECOND-MOEMNT CLOSURE MODELLING OF SEPARETING TURBULENT FLOWS) https://www.researchgate.net/publica...port_Modelling So, I tried method that modified Launder-Gibson-RSTM turbulence model to Hanjalic model. I did the following two things. 1) make a character definition (aij, A eij, E etc..) in Hanjalic.C. ex) Code:
volSymmTensorField aij = ((R_/k_)-(2/3)*I); ex) Code:
Y = - C2_*Fe*epsilon_*(epsilon_-D)/k_ But, that model diverge soon. So, I have a question. 1) Is that way to create new RSM corrected ? 2) Is that way to make a character definition corrected ? I don't know whether to tell it well, please give me advice. Please forgive me my lousy English. Your help is highly appreciated:) Thanks! oda |
please help me
anyone, help me:(

OpenFOAM is easy to modify and develop, the issue occure when the bugs start causing divergence although the physics behind the modeling is correct. |
modify turbulence model
Hi Ash!
Thanks you for your reply. Sorry for lack of words. I could use other software for Hanjalic and Jalirlic model. So, I want to use that model in OpenFOAM. Though compilation is successful, diverge quickly. I don't know whether corrected file and how to modify is right or not. Please give me advice. Thanks! oda |
