Hull/Appendage/Propeller Interaction Experiment,

Abstract

Three component Laser Doppler Velocimeter surveys were made in the thick boundary layer of the aft portion of an axisymmetric body. The experiment was conducted in the open jet of the David Taylor Research Center's Anechoic Flow Facility. Various appendage configurations, and an operating propeller were used to examine the interaction of hull, appendage and propeller induced flows. Velocity measurements were made at four different transverse planes along the hull longitudinal axis. For all the appendage configurations, more than twenty-seven million velocity components at six thousand locations were measured. Velocity results are displayed in vector and contour plots of the flow fields at each transverse plane. Harmonic analysis of the velocity variations is also used to further define the measured flow field behavior. Keywords: Submarine hull appendages; Marine propellers; Laser velocimeters; Three component velocity measurements; Wind tunnel tests; Hull and appendage flow interactions. (edc)
