Model Tests of Waterjet Propelled Delft 372 Catamaran

This document reports the activities and the tests that have been carried out in partial fulfilling of the sub agreement for "Validation of HPC/CFD-Based Variable-Physics Global Optimization for Waterjet Propelled High Speed Delft-Monohull", P.O. 1000705389, Req. ID No. W000132322, G/P No. 1 48099 00 01, C.F.D.A. No. 12.300. The full activity is founded by the Office of Naval Research. The Delft Catamaran project 372 was used as a basic hull shape form and a model was designed, manufactured and tested by Bulgarian Ship Hydrodynamics Centre (BSHC). Results were reported on Doc. KP092996/01-Rev. 0 (BSHC ref). Then the whole equipment was shipped to CNR-INSEAN in Rome (August 2010). Having in mind that the main goal of the present sub agreement is to produce a highly accurate set of EFD data to be used in the optimization field, the model has been used at INSEAN for the waterjet-equipped catamaran model performance testing, in compliance with the ITTC Waterjet Model Testing procedures 7.5- 02-05-03.1. A full comparison with BSHC data is reported: accordance and disagreement between the two data sets are discussed and commented.
