Free Surface Analysis

Using the volume of fluid (VOF) model, Ansys Computational Fluid Dynamics (CFD) can predict the location of the free surface interface location and its effects between two or more phases.

Interphase transfer of mass (phase change), species, energy, and momentum, including surface tension, can also be included, allowing the modeling of numerous multiphase flow conditions.

CFD Consulting Projects

Biomedical Device

Analyzed the atomization of a liquid stream into droplets before automated sorting, which captured the laminar surface tension-driven breakup at the free surface.

Large Ocean Vessel

Calculated the transient pressure and shear loading on a large ocean-going vessel while moving through different sea states.

Spin-coating

Calculated the film distribution and thickness during the spin coating process at various rotational speeds and therefore high g-force loaded films for various viscous liquids.

Mixing Tank

Calculated the height deformation of a free surface with its vortex calculation from added momentum of a high-speed impeller in a biomedical mixing tank.

Water Storage Tanks

Predicted diurnal flow patterns to ensure effective water replacement in a wastewater storage tank.
