v.Particle

v.Particle is an extension of v.Flow that allows simulating particulates that are embedded in the incompressible, turbulent fluid. 

The software provides the options to treat the particles as scalars (simple advection along streamline), one-way coupling to the flow field (where the fluid exerts forces on the particulates) and two-way coupling (both particulate phase and fluid phase affect each other).

v.Particle Features

 

  • Lagrangian modeling of particulates

 

  • Particle trajectory and tracing capabilities

 

  • Scalar (free advection–no phase coupling), one-way, or two-way coupling between fluid and particulate phases

 

  • Multiple choices of drag laws for particulate phase

 

  • Options for additional physics

 

  • Options for a variety of boundary conditions

 

  • No additional turbulence modeling required. Time accurate simulation of particulates in turbulent flow is automatic

 

 

We have utilized v.Particle in two of our recent research projects in the field of particulate mixing and the simulations went beyond previous analyses to reveal heretofore unobserved aspects of the mixing layer vortices.
