Resumen:
The interaction of solid particles with a solidifying interface is studied with numerical and analytical models forthe drag and pushing forces. The numerical results of the drag force on a spherical particle and planarinterfacewere compared with the forces given by both, the Stokes and Modified-Stokes equations. The pushing force wascalculated employing the Casimir-Lifshitz- Van der Waals force. The results show the range and degree of validity ofthe Stokes and modified Stokes equations for large and small separations.From there, it is shown that the particleinterfaceseparations for steady pushing obtained numerically, for the same particle radius and solidification velocity.In addition, the critical velocities obtained with the present hybrid model are compared with experimental resultspublished in the literature.
