Hi, all,

I hope some help. I am simulating some channel flows and pay more attention to the velocity of the center line. I hope to build a model to explain some special flows with complex geometry. At the beginning, I simulate a simple square flow with a Delta between the boundary and the lattice. I find that the velocity of the center line is not linear when the relaxation time is greater than 1. Is there anyone do this kind of simulations ? Please describe your results, especially the velocity of the center line. Thank you very much.
