Summary

The numerical simulations presented in this paper are performed with the commercial CFD-software Fluent (V. 4.5.1). It is based on the iterative solution of a two-phase flow formulation in which the first phase, denoted as “fluid”, is assumed to be the air and the second phase, denoted as “granular”, the molding material sand. As both phases are treated as a continuum the eulerian formulation of the conservation equations for momentum and mass is used. In contrast to the common eulerian two-phase approaches special emphasis must be placed (i) on an additional pressure term for the granular phase, namely the “solid pressure”, (ii) on the viscosity formulation for the granular phase taking into account the complex interaction of the sand, (iii) on the formulation for the momentum exchange between air and sand, and (iv) on adequate wall boundary conditions for the granular phase. Details of these items are given below.
