Summary of Two Independent Performance Measurements of the ONR Axial Waterjet 2 (AxWJ-2)

Abstract

This report presents the experimental axial flow waterjet measurements of the ONR AxWJ-7 conducted by Rolls Royce Naval Marine and the Naval Surface Warfare Center Carderock Division. While the details and the data of these two experiments can be found in separate reports, the purpose of this document is to provide an all-in-one comparison of their findings, to be used by researchers across the hydrodynamic field in the public domain. This report aims at providing waterjet information to those in both the experimental and computational fluid dynamic realms to establish the ONR AxWJ-2 as a benchmark design, to further the development of waterjet-related design, to fu design and analysis tools, and for validation purposes. Discussion is provided regarding each facilities geometry, setup, and measurement techniques. Comparisons are made between the datasets highlighting disparities in the results. Differences between the results were attributed to Reynolds scaling effects, rotor tip clearance, and testing procedures.
