Abstract

Ship flow experimental database for RANSE codes validation A.Olivieri, F. Pistani, R. Penna INSEAN (The Italian ship model basin) Roma, Italy 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
