Description
Summary:The present work deals with the numerical simulation of accelerating and decelerating motions of a submerged body of revolution, in order to investigate the influence of the thrust variation on the maneuvering characteristics. A finite volume method is adopted to solve the essentially 2D RANS, time-dependent equations in a body-fitted co-ordinate system. Two problems have been examined for a 50m body of revolution: (a) the stopping maneuver, i.e. crash stop from steady forward speed and then full astern and (b) full ahead at steady speed from rest and then full astern.
