Boundary conditions

MeteorologyChemistry & transport
surfaceNo-slip prescriptions for velocity apply. In the case of turbulent flow calculations with particular turbulence models, a special mathematical representation of the near-wall flow is employed. This consists of algebraic ‘wall functions’, hybrid wall functions, two-layer models or low Reynolds number models.
topSymmetry plane: the normal velocity and normal gradients of all other variables are zero.
lateral inflowInlet(Prescribed Flow): the inflow conditions are imposed by the user (velocities, turbulence parameters).
lateral outflowOutlet: The gradients of all variables along the flow direction at the outflow surface are taken to be zero and the exit mass flow is fixed from overall continuity considerations.
