Dispersed particle flows can also be modeled as an Eulerian phase, allowing applications such as granular flows in fluidized bed reactors to be modeled. The Solid Pressure Force model is available for granular flows approaching the packing limit, and particle size distributions can be handled using the S-Gamma model.
With the release of STAR-CCM+ v8.02, reactions can be simulated both between phases and within a phase.
Boiling can be modeled both at the wall and in the bulk fluid, and mass transfer between phases due to dissolution can also be modeled.
Within this Eulerian framework, STAR-CCM+ has the Volume Of Fluid (VOF) model which is used for the simulation of immiscible free surfaces, such as the development of waves around a ship hull (and consequential drag), or slugging flow in a pipe. To assist in the setting up of VOF cases, the model allows you to define VOF waves which are then used to initialize the VOF calculation and to provide suitable profiles at boundaries, vastly simplifying the setup of such cases. These waves can be superimposed to allow for the modeling of any scenario.
Also within the Eulerian framework, the Fluid Film model allows thin fluid films to be modeled on the surface of your geometry. Typical applications include vehicle soiling, aircraft (anti) icing, oil films on the internal surfaces of automotive engines and gas turbines, spray-cooling systems, and ink-jet printers. The fluid film can interact with other phases, accepting impinging droplets from Lagrangian phases and allowing droplets to be shed by film stripping. The film can condense from and evaporate to Eulerian phases and boiling of the film can also be modeled.
In addition to the comprehensive physics of the Eulerian Multiphase Model, the ease-of-use for streamlined setup of complex multiphase problems makes STAR-CCM+ a preferred solution for Multiphase applications.
