03/31/2022, 9:19 AMthat is my idea - k

03/31/2022, 9:20 AMat the moment i'm stuck with RAS, and even with that i can't affort low-Re meshes. gives okayish results and that i have to live with - k

03/31/2022, 9:21 AMYOLO - u
uemalkocoglu
03/31/2022, 9:29 AMthen, you have no problem - u
uemalkocoglu
03/31/2022, 9:29 AMseems positive - k

03/31/2022, 4:05 PMIn this inlet pressure BC I want to change pressure with number of iterations so I am giving table as input but still the pressure is not changing - s

04/01/2022, 4:53 AMWhen I arrived home, I checked my books and "Numerical Techniques for Direct and Large-Eddy Simulations" by Xi Jiang & Choi-Hong Lai (CRC Press, 2009) would be good on both LES and DNS - u
uemalkocoglu
04/01/2022, 4:54 AMIt covers LES and DNS for not only incompressible flows but also compressible flows - u
uemalkocoglu
04/01/2022, 4:55 AMFor RANS models, "Fundamentals of Turbulence Modeling" by Ching-Jen Chen & Sheng-Yuh Jaw provides lots of details from derivation of turbulence models to determination of model coefficients - u
uemalkocoglu
04/01/2022, 4:56 AMIt would be another "bible" for RANS perspective - u
uemalkocoglu
04/01/2022, 4:56 AMI hope that they would be beneficial for our group - u
uemalkocoglu
04/01/2022, 4:58 AMAaaand, how could I forget, "Turbulence Modeling for CFD" of Wilcox - u
uemalkocoglu
04/01/2022, 4:59 AMProbably everyone dealing with RANS knows that resource but I could not conclude my messages without mentioning it - s

uemalkocoglu
04/01/2022, 7:48 AMYeah, I also have it. Begins with necessary definitions - s
slopezcastano
04/01/2022, 7:49 AMOne nice feature! - u
uemalkocoglu
04/01/2022, 7:49 AMBut that is totally new for me - u

04/01/2022, 7:49 AMThank you the master @slopezcastano - s

04/01/2022, 7:51 AMThere is an even better book on LES/DNS, but it is damn difficult to find: https://www.abebooks.com/9781930217072/Elements-direct-large-eddy-simulation-Geurts-1930217072/plp - s
