Resumen:
The modelling of liquid flow in gas-stirred vessels is described. A
simple two-phase model accounts for the buoyancy effect of bubbles.
Friction between liquid and gas is modelled with the hypothesis of
independent bubbles. The resulting PDE system is discretized with an
original version of the SUPG-FEM technique which stabilizes both the
convection term and equal-order interpolations for velocity and
pressure, which are known to be unstable for incompressible flows. The
resulting steady state discrete system is solved via pseudotemporal
explicit iteration with a local time step and a preconditioning to
homogenize the temporal scales for liquid and gas.
