Turbulence Modelling RSM - Stress BSL

ranger85 · June 28, 2018, 05:48

Hello everybody,

for comparison I want to chosse a Reynolds Stress Model with Stress BSL option. But unfortunately I can´t find any Information about its advantages/disadvantages wall Treatment and the theory behind it.
Can anyone tell me where I should look?

Thank you in advance and best regards

Hi,

Although I can't provide any valuable written resources yet, I found it a bit intriguing. I do use it for developing fully turbulent pipe inlet profile to be implemented as an input to some other LES/DNS computations. What I found is that it underestimates turbulence intensities quite significantly especially in a flow-normal direction.

I wonder if there are other forum-members who could share their opinion or add some valuable references to the topic.

Regards
Piotrek
