! Purpose: compute convective fluxes for RaNS class turbulence model, depending 
!          on model selected, and add them to dissipation in order to obtain 
!          the residual.
!
! Description: none.
!
! Input: region = data of current region.
!
! Output: region%levels%turb%rhs = turb convective fluxes + turb dissipation.
!
! Notes: none.
