Model Study of Suction Head, Dredge Jadwin
Abstract
The study reported herein was conducted by the Waterways Experiment Station for the Memphis District, Corps of Engineers. The purpose of the study was to investigate by means of a small-scale hydraulic model the performance of a newly-designed suction head for the dredge JADWIN, and to obtain data and information on the operation of both original and new-type heads constructive toward achieving a design of maximum efficiency. Two basic types of suction heads were initially scheduled for study: the original flared-wall double-dustpan head and a new-type single-dustpan head designed by the Memphis Office. Subsequently, tests were also made of a straight-line modification of the original double-dustpan head. The study included investigation of such design considerations as: the effect of baffles installed in the suction heads and suction lines; the effect of changed alignment of the side walls; the change in output that might be effected by changing the number of regular jets, or by the addition of end jets; the effect on dredge operation of changing the floor design from a flat floor to one with a raised center section; and determination of the optimum ratio between the cross-sectional areas of suction-head opening and suction pipe.
