ComFLOW home page
ComFLOW is a simulation method for free-surface flow in terrestrial
and micro-gravity environments. The latter is the maiden application of the method (formerly known as ComFlo). It models viscous two-phase flow (incompressibleliquid, compressible gas) in and around arbitrary geometries. Effects of capillarity are included. Also liquid-solid body interaction is included in ComFLOW.
A major application area -- in cooperation with TU Delft, MARIN, FORCE Technology, Deltares and several offshore related companies -- concerns the prediction of hydrodynamic wave loading on ships and offshore platforms. For validation purposes, at MARIN a series of experiments is carried out: green water on deck (dambreak), CALM buoy, moonpools, falling life boats, etc. Details about the dambreak experiments can be found here.

A former application area (in cooperation with NLR) concerns spacecraft
dynamics as influenced by onboard liquids. Validation experiments have been
carried out in February 2005 with the bespoke Sloshsat FLEVO spacecraft.
A short overview of this early space history of the development of ComFLOW (originally called Comflo) can be found on its space-history page .
As a side-line spin-off project, a version has been developed to model hemodynamics in elastic arteries.
A detailed description of the mathematical and numerical modelling
inside ComFLOW can be found in the PhD theses of
Jeroen Gerrits (December 2001),

Some ComFLOW animations of free-surface flow can be found at our
CFD gallery.
A historic account of our cooperation with the space and offshore industry can be found in this document.
A powerpoint presentation with an overview of the status of ComFLOW in 2019 can be found
