Progresses in Particle-Laden Flows Simulations in Multistage Turbomachinery With OpenFOAM

Abstract Numerical simulations of particle-laden flows have received growing attention in the last decade, due to broad spectrum industrial applications which discrete phases prediction is interest. Among these, ingestion particles by turbomachinery an area that seeing vivid research and studies. The most common technique tackle this kind problem Eulerian–Lagrangian method, individual are tracked inside domain. At same time, multistage simulation interfaces needed couple flow solution adjacent domains relative motion. In work, open-source extension for Lagrangian rotating machines presented foam-extend environment. First, a thorough discussion implementation presented, with particular emphasis on particle passage through general grid (GGI) mixing planes. Moreover, mass-conservative redistribution described, as such property requested at between multiple reference frame (MRF). peculiarities algorithm then shown relevant test case. Eventually, three complexity, show capabilities numerical code real-life applications. Simulation results terms erosion impacts aerodynamic surfaces also examples possible parameters interest computations.
