Simcenter STAR-CCM+ multiphase CFD simulation fact sheet

A five-page fact sheet on multiphase CFD in Simcenter STAR-CCM+. It explains why classical models designed for a single flow regime struggle with industrial systems that combine mixtures, free surfaces, sprays and liquid films, and how hybrid and multiple regime modelling address this, with examples such as vehicle water management, e-motor cooling, gear lubrication, multiphase pumps and dishwasher fluid management.

What the document covers

• The range of models and their typical uses: volume of fluid (VOF), mixture, Eulerian and dispersed multiphase, fluid film, Lagrangian multiphase, discrete element method (DEM) and smoothed-particle hydrodynamics (SPH)
• Hybrid multiphase: transitions between fluid film and VOF, VOF-Lagrangian modelling of jet breakup, and Lagrangian droplets impinging on and stripping from films
• Additional physics such as boiling, cavitation, reactions and population balance models for droplet and bubble sizes
• The large-scale interface (LSI) model and multiple regime model, which let free surfaces and mixtures coexist and allow phase inversion
• The mesh-free SPH solver, with HPC and GPU support, for sloshing, drivetrain lubrication and liquid run-off
• Model-based adaptive mesh refinement and adaptive time stepping to reduce computing time
