Abstract
A detailed description of the flow around a fast displacement ship is given in
terms of mean velocity components to provide a useful benchmark for CFD
validation. The measurements have been performed at the INSEAN basin n. 2
that is 220 m long, 9 m wide and 3.5 m deep. A specially designed five holes
Pi tot probe for side hull measurements has been adopted to reach all the regions
of the flow field. The tests have been carried out at Froude number 0.28
corresponding to a model length of 5.72 m and carriage speed of 2.097 m/s.
Measurements of the three mean velocity components have been performed on
10 cross- sections along the model. Furthermore, the regions that presented trace
of particular flow structures have been analysed in detail. In those cases, the
measurements have been repeated, adopting finer grids. A deta
