Resumo(s): | This work describes the implementation and assessment of the wall slip boundary condition in a 3D numerical modelling code, based on the finite volume method, that is being developed by the research team. Several phenomenological models relating the velocity and the shear stress at the wall were implemented. The capabilities of the new numerical code are illustrated with three case studies where the wall slip boundary conditions play an important role, namely the flow in a smooth contraction, the stick-slip phenomenon an the flow in a profile extrusion die. The results obtained are qualitatively in accordance with the theoretical expectations and evidence the importance of wall slip. |
