Description/Abstract

Attempts to predict the motions of small, high speed craft in waves require accurate estimation of the forces acting on the hull of the vessel as it enters the water. Improvements to the use of 'strip theory' in predicting the motions of such craft have focused on using two-dimensional computational fluid dynamics (CFD) to predict more accurately the forces experienced by a wedge on entry to water. In order to validate the CFD calculations fundamental experiments have been undertaken using measurements of pressure, acceleration and position synchronized with high speed video images (up to 6000 fps). These experiments provide information in sufficient detail to allow a thorough validation of the CFD. The CFD techniques adopted may be applied to any ship section geometry. An overview will be given of both the CFD techniques and the experimentation.
