Estimation of First Grid Point Near Wall
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???
