Boundary conditions for smooth walls (icodcl = 5).
file cs_boundary_conditions_set_coeffs_turb.c
The wall functions may change the value of the diffusive flux.
The values at a boundary face \( \fib \) stored in the face center \( \centf \) of the variable \( P \) and its diffusive flux \( Q \) are written as:
\[ P_{\face} = A_P^g + B_P^g P_{\centi} \]
and
\[ Q_{\face} = A_P^f + B_P^f P_{\centi} \]
where \( P_\centi \) is the value of the variable \( P \) at the neighboring cell.
Warning:
\[ \vect{u}_{\face} = \vect{A}_u^g + \tens{B}_u^g \vect{u}_{\centi} \]
and\[ \vect{Q}_{\face} = \vect{A}_u^f + \tens{B}_u^f \vect{u}_{\centi} \]
where \( \tens{B}_u^g \) and \( \tens{B}_u^f \) are 3x3 tensor matrix which coupled velocity components next to a boundary.Please refer to the wall boundary conditions section of the theory guide for more informations, as well as the clptur section.
