Some questions about the DNS of turbulent channel flow

[jushi-123]

Dear Incompact3d developers,

I have a question to consult you. Is there any tips for the parameter setting of high Re turbulent channel flow, such as Re number/bulk velocity/initial noise and so on. For example, I want to run a DNS of turbulent channel flow with CFR(Retau=590)，could you give me some suggestions about these parameters? I have attached my input file below.

I'm looking forward to your reply, thanks!

Hi,
Please have a look at https://github.com/xcompact3d/Incompact3d/blob/master/examples/Channel/stretching_parameter_channel.f90. It is a small code to work out what input Reynolds number is needed for a given Re_tau. It will also tell you what stretching parameter to use.
Best,
Sylvain
