New capabilities in modeling multiphase flows using the Eulerian Multiphase (EMP) model are demonstrated by examples. These new capabilities include granular model for multi-size particle flows, RSM for turbulent multiphase flows, multi-component boiling model for evaporation of chemical species and the Adaptive-MUSIG (A-MUSIG) population balance model for poly-dispersed flows.
An overview is presented of key methodologies in STAR-CCM+ and STAR-CD for simulating disperse multiphase flows involving droplets, solid particles and/or liquid films, including: atomisation; particle dynamics and heat/mass transfer; wall impact and erosion; and liquid film dynamics, heat/mass transfer and melting/solidification. Examples are shown of validation studies and applications in the aerospace, automotive, oil/gas and manufacturing and medical fields.
The presentation describes the evolution of features made available in recent releases and new capabilities that will be available within the forthcoming v4.22 release and their application to in-cylinder engine calculations. These include: Further development of combustion models including dual-fuel combustion such as diesel-natural gas; Support for 3rd party chemistry within the advanced ECFM and PVM-MF combustion models; Crank-angle resolved Conjugate Heat Transfer (CHT) analysis and automated meshing using STAR-CCM+.
Discrete Element Method in STAR-CCM+ allows modeling solid handling and processing applications with or without coupling to fluid flow. This presentation reviews the DEM capabilities in STAR-CCM+.
