Modelling Spillage in Rotating Cutter Suction Heads: A combined Finite Volume and Discrete Element Model

Due to an increased demand for transport, ships become larger, needing a larger navigable depth. For these reasons a waterway needs to be dredged and a Cutter Suction Dredger is a vessel suitable for this operation.<br/><br/>A Cutter Suction Dredger is a floating vessel which removes sand, clay or soft rock from sea or river beds. It has a...

Numerical simulations of flapping foil and wing aerodynamics: Mesh deformation using radial basis functions

Both biological and engineering scientist have always been intrigued by the flight of insects and birds. For a long time, the aerodynamic mechanism behind flapping insect flight was a complete mystery. Recently, several experimental and numerical flow visualisations were performed to investigate the aerodynamics around flapping wings. Flapping...
