I am writing a cod for solving turbulent 2-D channel flow using this method for each relative part
finite volume method
standard wall function
as you know for standard K-e y+ must be greater than 11.63.
when i adjust the first nodes distance fom the corresponding wall to y+ become greater than 11.63 the code go to diverging.
but when y+ is less than 11.63 it hasn't any problem.
does anyone know about this problem?
and i wanna know about treatment for V-velocity in cells near the wall.
how mus i treat for V boundary condition?
