Experimental Studies of Spray Patterns and Thrust Characteristics Produced by Vertical Disc Thrusters Above Water Surface.

Abstract

This report is in two parts, and it describes two separate, but closely related, studies of the interaction of a vertical thruster and a water surface. The first study was conducted at DTNSRDC and involved investigations of the effects of thrust loading, height, tilt and surface waves on spray patterns. The data were interpreted in a separate effort at VPI and SU. The main effort at VPI and SU was concerned with droplet size measurements in the spray as a function of thrust loading, propeller diameter and height. The experimental study was planned on the basis of formulation suggested by dimensional analysis. (Author)
