Transitional pipe flow

[Madhurjya814]

Hi, can I use the pipe flow code for Re=2000-4000 which generally falls in the transitional regime? What are parameters that are important for transitional flow simulations? Thank you.

Yes you can, but you might have to adjust the size of the domain in the streamwise direction and possibly the time step.
Best,
