solving turbulent flow
 

HI All.

I am writing a code for solving turbulent flow in a channel on collocated grid using STANDARD K-E.

Could you tell me that yplus ( that computed in first row near the wall )
how much must be?

about 30, about 13 ?

upper than 11.62 necessary ?

is that must be only upper than 11.62?
for example if it is 15 have no difference if it is for example 30?

and how many nodes dose grid need?

do you have any result as benchmark.

i am waiting for your help.
