Abstract
Experiments were carried out in the NAE flow visualization water tunnel with small submarine models representing the parent form of a systematic series. Two techniques were employed: aluminum tracer particles in the flow, and dye injection from the model. The Reynolds number was between 4XE4 and E5 based on overall length. These tests were conducted to identify the major flow mechanisms and interactions. Both qualitative observations and some quantitative results are reported. The flow was generally dominated by the presence of a sail of placement of the foreplanes. The use of flow visualization is especially valuable since such flows are too complex for simple methods of analysis.
