Research on Main Injection Scoops and Overboard Discharges

摘要

A very brief discussion of the hydrodynamics of scoop flow is given. An analysis of available ship and ship-model boundary layer data is presented and the influence of the boundary layer momentum thickness and shape parameter on the flow to the scoop is discussed. An account of the equipment built at the Model Basin for this project is rendered by reference to sketches, figures and working plans. Three families of scoops were derived mathematically from three different parent designs. No test data were obtained because of the low priority assigned this work and it is therefore concluded that the entire project be re-evaluated and contracted to another laboratory in order to accomplish the desired test work.
