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 incompressible flow in and around arbitrary geometries. At the free surface continuity of stresses is imposed; effects of capillarity are included. Also liquid-solid body interaction is included in (some versions of) 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 Sloshsat FLEVO satellite.



Finally, a ComFlo 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), Erwin Loots (May 2003), Geert Fekken (March 2004), Theresa Kleefsman (November 2005), Rik Wemmenhove (May 2008), Peter Wellens (Jan 2012), Bulent Duz (September 2015), Peter van der Plas (March 2017), and Henri van der Heiden (March 2019).
