Abstract
This thesis conducts an experimental investigation of the effects on separation of the closing angle of the stern section, the depth of submergence or proximity of the free surface, and the speed of a submerged body of revolution. The results of this investigation are then compared to the results obtained from two existing theoretical criteria for the prediction of the separation point on such bodies in turbulent flow. The point of separation is observed experimentally by photographing dye-flow patterns over the stern of the model at three speeds from .75 to 1.7 knots, at three depths of submergence corresponding to surfaced, near surface and fully submerged conditions for five different body stern shapes increasing in streamlining from a blunt hemisphere to a finely shaped almost pointed section. Equivalent body profiles to the outside of the turbulent boundary layer displacement thickness are computed and potential flow pressure- velocity distributions based upon the equivalent profiles are calculated and used in evaluating the separation criteria.

    Bottom and surface proximity effects on the added mass of Rankine ovoids. 

    Fickel, Monty George. (Monterey, California. Naval Postgraduate School, 1973-12);
    The free-surface and bottom-proximity effects on the added mass of Rankine ovoids of various length-to-diameter ratios were experimentally investigated by vertically oscillating the ovoids normal to their major axis. The ...

    Added mass of a circular cylinder under a free surface 

    Gosselin, Richard Leon (Monterey, California; Naval Postgraduate School, 1971-12);
    When a circular cylinder is immersed in a fluid of infinite extent and oscillated in such a manner that drag effects are negligible, it is well known that the closed form solution gives an added mass coefficient of 1.0. ...

    Numerical analysis of single-vortex/free-surface interaction 

    Merrill, Craig F. (Monterey, California. Naval Postgraduate School, 1993-12);
    The interaction of a single Lamb vortex with a free surface is analyzed numerically through the use of a finite-difference technique. The individual effects of gravity, viscosity, and surface tension are investigated within ...
