SlenderFlow software uses slender-body theory to calculate the flow of water around ships. It is developed by Dr Tim Gourlay at Perth Hydro, and used for our ship hydrodynamics consulting. As a potential-flow code, it is very numerically efficient, with computation times typically a fraction of a second.
Commercial track record
The methods in SlenderFlow have been successfully used in many commercial projects, including:
SlenderFlow methods have been validated against a wide range of model tests from the European shallow-water towing tanks at Flanders Hydraulics, DST Duisburg and BAW Hamburg. The international "PreSquat" blind validation workshop of 2013 showed that SlenderFlow methods produced consistently accurate squat predictions.
Full-scale ship motion trials have now been undertaken on over 60 cargo ship transits through shallow channels in Hong Kong, Torres Strait, Geraldton and Fremantle. The results have been used to validate and refine SlenderFlow for application in shallow shipping channels.
SlenderFlow may be used for any displacement (non-planing) vessel, including ocean-going commercial and military vessels, European inland vessels, catamaran ferries and trimaran ferries.
