Simcenter STAR-CCM+
Comprehensive suite to model real world multiphase flows
Real-world engineering problems cover multiple flow regimes across stratified, dispersed, discrete, films, etc. To date, there is no single multiphase model that can cover all regimes, however, Simcenter provides a comprehensive range of models which can be used together to cover many flow regimes including the transitions between them. Predict and understand real-world behavior of your products by simulating multi-regime, multi-scale multiphase flows.
Multiphase Flow is made up of powerful features that allow you to build a custom solution.
Cavitation
Cavitation occurs where rapid changes of pressure in a liquid lead to the formation of vapor-filled bubbles in regions of low pressure. When subjected to higher pressures, these bubbles can collapse forming shock-waves that can deteriorate performance or damage equipment. Simcenter STAR-CCM+ allows you to predict the occurrence of cavitation in liquid systems and either mitigate it or turn it to your advantage.
Discrete Element Method (DEM)
Simcenter offers industry-leading Discrete Element Method (DEM) capability to model non-spherical particle behavior. Unlike most codes, the particle behavior can be coupled with flow and moving bodies in a single package, eliminating the need for expensive multiple software tools and reducing time and cost. The DEM model is widely used to simulate fluidized beds, rock mechanics, conveyors, tablet coating, plugging fissures in oil wells, crop harvesting, and lawn mowers.
Dispersed Multiphase (DMP)
The DMP model is a lightweight Eulerian model suitable for modeling low loadings of small droplets/particles where the dispersed phases to not contribute to the volume fraction. This model is efficient in automotive soiling and aircraft icing applications.
Eulerian Multiphase (EMP)
A core model for simulating continuous, interpenetrating and reacting fluids. Model phase change, crystal growth and bubbles/droplets. Applications include bubble columns, fluidized beds, settling tanks and mixing vessels.
Fluid Film
Model thin layer of fluid on surfaces and capture rivulets and surface tension effects with this model. Include phase-change effects like evaporation, condensation, melting and solidification to accurately simulate your physics. Applications include vehicle rainwater management, selective catalytic reduction (SCR), fuel sprays, spray coating/deposition and aircraft ice protection.
Lagrangian Multiphase (LMP)
Accurate solve the path of discrete droplets or particles in dilute dispersed phases. Include droplet splashing, rebounding, atomization and breakup, evaporation, condensation and reactions to fully model the exact physics. Applications include vehicle water management, selective catalytic reduction (SCR), spray coating, erosion and liquid fuel combustion.
Mixture Multiphase (MMP)
Utilize this lightweight model that is faster than EMP by solving one set of transport equations and assuming phases to be miscible. Applications include phase changes in fuel cells, nuclear steam generators, and boilers.
Multiphase Interaction Models
Multiphase flows are never occurring in isolation and hence accurately capturing the interaction between different phases is key to minimize computational cost. Simcenter offers the use of all multiphase models together in a single simulation to capture real-world multiphase flows. Use the highest fidelity model or combine several models to cover all regimes, in addition to expanding the applicability of a standard model.
Volume of Fluid (VOF)
Accurately track the motion of the interfaces between immiscible fluids and model phase change effects like boiling, evaporation, condensation, cavitation, solidification and melting with the VOF model. Suited for engine cooling, oil and gas flow assurance problems, fuel tank sloshing and marine hydrodynamics and seakeeping (with predefined VOF waves.)
