Abstract

Abstract:

A seven-hole probe velocity measurement system is developed in this paper, which consists of SHP rake, multi-channel pressure transducers, data acquisition system (16bit A/D) and software. Flow field properties of the aft-deck is studied by making three-dimensional full-scale measurements of a destroyer. The flow field vector maps are given. The results of this study will also provide an experimental datum, from which the safe operating envelope can be worked out; it may also be used to validate computer fluid dynamic predictions.

Key words: sh ip fligh t deck, flow field, full-scale measurement, seven-ho le p robe
