To define a porous wall condition on a boundary section, follow these steps:
Select the Porous wall menu item in the list of boundary condition choices.
Porous wall
Select the law you want to use and specify the related parameters:
To use Equation 8–12 (the default), select F(v) = Power law.
F(v) = Power law
Then specify constant values for k (
) and e (
). To use Equation 8–13, select F(v) = Threshold law.
F(v) = Threshold law
Then specify constant values for k (
), k2 (
), and yc (
). To use Equation 8–14, select F(v) = Asymptotic law.
F(v) = Asymptotic law
Then specify constant values for k (
) and vc (
).
