Estimation of First Grid Point Near Wall -- CFD Online Discussion Forums

April 24, 2006, 13:00	Estimation of First Grid Point Near Wall	#1
Amer Mahmood Guest Posts: n/a	Hi, Iam simulating flow in a rectangular channel and using enhanced wall treatment in Fluent. For estimation of Ist grid point (y+=1) I am using the following relation: y+=(density)(yp)(turbulent velocity)/(dynamic viscosity) turbulent velocity = average velocity * SQRT(Cf/2) where yp = distance from the wall Cf = friction coefficient Is this process fine???
