Multiphase flow based on OpenFOAM®’s volume of fluid method

Turbulent transient vortex shedding behind a plate with holes in a chemical plant. Eddy transport simulation using LES (Large-Eddy-Simulation) in OpenFOAM

Water droplets are evaporating in a quenching device. Strong coupled interaction with heat transfer, multiple species transport, species mass transfer and parcel based particle modelling.

Moving mesh applications with free surfaces are very computational intensive.

Valve with a sliding mesh approach

Two phase Euler-Euler simulation

Virtual sudden color change in an optimized PVC extrusion die showing a very uniform residence time of the non-Newtonian melt within the die

Bag filters are loaded with dust particles, hereby changing the outflow velocity depending on the current load.

Water-Air simulation with VOF on a blockMesh grid

CFD filtration simulation for bag filter system on macro scale based on OpenFOAM. The simulation tools make it possible to pursue different damage hypotheses and to evaluate and assess the particle input on the filter both locally and integrally for a filter as a whole.

Valve example: Solved with DHCAE’s OpenFOAM -CalculiX coupling

The animation shows an example of the ACMI functionality in OpenFOAM which allows sliding meshes and partial overflow in the resulting transition zones. Here the motion is combinded with piston movement.

Filter application: Transfer of the microscale approach (calculated with DNSLab above) to a mesoscale model with porous structures in OpenFOAM (below)

Meso-Scale filter modelling: Considers the cake generation by a porous zone. The resistance is estimated by the Ergun-equation depending on the local particle size resulting from the individual settling in the cells.

OpenFOAM CFD analysis cleaning with sprays: Lagrangian sprays, film formation, stripping of droplets

Automated cloud-based CFD simulation for propeller duct optimization: CFD Tool based on OpenFOAM

OpenFOAM VoF-to-DpM atomization with isoAdvector and adaptive mesh refienemt (AMR): Swirl nozzle spray validation. Very good agreement with empirical droplet-size correlation

OpenFOAM VOF-to-DPM extension for spray atomization | flat-spray nozzle Simulation for car wash application
