Ansys 2021 R1: Multiphase Volume Of Fluid (VOF) and Regime Transition Update

Ansys Fluent provides the widest range of multiphase models to accurately simulate your toughest challenges. Learn about recent innovations, including:

  • A VOF multiphase model that delivers robust free surface flow simulations with enhanced user experience, unique pressure discretization numerics, automated solution stabilization and solution acceleration techniques.
  • Eulerian Multi-Fluid VOF, AlAD (Algebraic Interfacial Area Density) and GenTOP (GENeralized TwO Phase) Models provide the key ingredients to systemically model mixed flow regimes and regime transitions in gas–liquid systems and gas–liquid flows. These flows often involve transient patterns, such as slug flow, annular flow, etc. These conditions often occur when more than one flow topology — droplet, bubbly or separated flows — exists, requiring unique special Eulerian Closure Modeling Techniques, sophisticated interface capturing methods and smart regime transition detection algorithms.
