Turbulence viscous-wall boundary values

SA (one equation)

Ghost working variable is the linear image of the interior so the wall value is zero:

\[\tilde\nu_g = - \tilde\nu_i\]

SST / k-omega

Kinetic energy uses the same image; specific dissipation follows Menter:

\[\omega_w = \frac{60\mu_l}{\rho\beta_1 d^2 Re}\]
