nanoFluidX - Background

Printer-friendly version

nanoFluidX is a software package developed by FluiDyna GmbH to simulate complex multi-phase flows. The underlying numerical method (SPH – Smoothed Particle Hydrodynamics) was originally invented for astrophysical problems but can also successfully by applied to free-surface flows and complex multi-phase problems with interfacial effects such as surface tension.

 

 

Sketch of an SPH discretization and the interaction with neighbouring particles.

 

Using SPH a continuum phase is discretized with Lagragian discretization points („particles“) and the dynamics of this phase result from interaction forces between neighbouring particles. This generalized approach offers the flexibility to model (almost) any physical phenomenon as these interaction forces can be formulated as complex as necessary. An important advantage of SPH is the meshless nature of the method – no cumbersome grid generation is necessary!

 

Origins of the code stem from Technical University of Munich's (TUM) Chair of Aerodynamics and Fluid Mechanics (Lehrstuhl für Aerodynamik und Strömungsmechanik), and the company remains in close relationship with TUM. All of the physical models implemented in nanoFluidX come directly from peer-reviewed scientific work, most of which originated directly at the mentioned TUM department.

 

Which physical effects can be simulated with nanoFluidX?

 

  • Free-surface flows in arbitrarily complex geometries
  • Temperature distributions (heating, cooling) in fluids/solids
  • Multi-fluid flows in channels and open geometries
  • Surface tension effects including surface wetting
  • ...

 

Potential applications of nanoFluidX

 

  • Oil splashing in a gearbox
  • Tank sloshing
  • Simulation of capillary flows in lab-on-a-chip devices
  • Microfluidic reactors and mixers
  • Surface wetting of fluids
