Hardware and Instrumentation of the DARPA SUBOFF Experiments

Abstract

DARPA has funded and coordinated a Computational Fluid Dynamics (CFD) Program to assist in development of advanced submarines/underwater vehicles. The ultimate goal of the DARPA SUBOFF Project is to develop fully matured CFD codes that are user-friendly, cost effective, and fully verified by detailed experimental comparisons. At present, however, experimental data for the flow field over an entire appended submarine are limited, making CFD validation difficult. Experimental measurements of the flow field of an axisymmetric body will be used to determine the current capabilities of the CFD community. The design and construction of two geometrically similar DARPA SUBOFF models are outlined. The hardware and instrumentation used to collect the experimental data in the David Taylor Research Center Anechoic Flow Facility are also summarized. Keywords: Hot wire anemometry; Boundary layer; Pressure distribution; Wake measurement; Shear stress.
