Abstract:

The research covered by this grant was directed toward developing a numerical method for computing wave drag on ship hulls of general shape. The research as originally proposed was to extend for three years, however only fifteen months of research were supported. In this time the soundness of the program of research as presented in the original proposal has been demonstrated and several objectives were met. The numerical method has been tested on several fluid flow problems and its accuracy and efficiency have been demonstrated. The wave drag has been studied on a simplified model of a ship, one lacking a bow and stern, and it has been found that the drag is qualitatively the same as that of a real hull shape. The basic numerical method is applicable to a wide class of problems involving a free surface associated with potential flow.
