CFD simulation hydraulic of counter-flow sieve tray (without overflow weir)

Abstract

Computational fluid dynamics has become one of the main methods for research anddesign ofsieve trays, however, the most common models, Euler-Euler phases, turbulence RANS, are based on empirical correlations for cross-flow trays with round holes. Our goal was CFD modeling of sieve tray witha countercurrent flows in the OpenFOAM program, a multiphase VOF model, and a kOmegaSSTDES turbulence model. The model can be used to simulate a low-intensity mixture mode of sieve tray, for example, for a water-air system, the superfical gas velocityis no more than 0.5 m/s.
