摘要
Abstract : The Submarine Technology Program Office of DARPA funded a concerted and coordinated computational fluid dynamics program to assist in the development of advanced submarines for the future. The DARPA SUBOFF project will evaluate, in a competitive environment directly against model test results, flow field predictions of an axisymmetric hull model with and without appendages. The model configurations were designed at DTRC and are given in this report. An axisymmetric body, fairwater, symmetric stern appendages, two ring wings and ring wing support struts were designed for DARPA SUBOFF project. Two geometrically identical models, designed to a linear scale ratio of 24, will be constructed to allow simultaneous testing in different facilities. Geometrical details of all components, including defining equations with computer code listings, are provided. The locations of velocity measurement stations and of surface pressure taps are also given. This information is intended for use by both the model test engineer and the CFD engineer. Keywords: Submarine hull models; Shroud struts; Pressure measurement; Geometric forms.
