A dual-time central-difference interface-capturing finite volume scheme applied to cavitation modelling

Cavitation is an important and dynamic area of research in many disciplines. Cavitation generally produces unwanted side effects such as noise and structural damage. Potentially cavitating flows occur, for example, around high-speed submerged bodies, propellers, nozzles and hydrofoils. Paper showed for first time that a standard, widely-used computational method from aerodynamics could be straightforwardly adapted to model cavitation. This allows existing software tools to be modified and pre- and post-processing capability to be retained. Technology was implemented within BAE Systems code SOLAR [contact: Director, Zenotech] and led to first-author Gough's PhD.
