HYDRODYNAMIC FORCES AND MOMENTS ON A SUBMERGED BODY OF REVOLUTION RESULTING FROM A FAIRWATER AND CONTROL SURFACES

This thesis involves an investigation of the hydrodynamic forces and moments on a submerged body of revolution, resulting from the addition of an asymmetric fairwater, and hull-control surfaces, and the results of their interactions. This investigation involved both experimental and numerical models. Experimental tests were performed in the M.I.T. Variable Pressure Water Tunnel on a fairwater model, with independently-controlled hydroplanes, and on a submersible model, whose configuration was systematically altered by the addition of a fairwater and control surfaces. Graphical results for both of these models are presented. Flow visualization tests were also performed on the submersible model in order to observe the change in flow past the body of revolution and control surfaces caused by the asymmetric fairwater and its resulting downwash. Photographic results of these tests are presented. A preliminary numerical model (Fortran language) for the prediction of forces and moments, based on potential theory and vorticity distributions, is presented and its results compared with those obtained experimentally.
