Background

Although air and sea vehicles are traditionally designed to develop attached flow at cruise conditions, they also routinely develop separated flows within the broader operating envelope, such as at maneuver conditions, and occasionally even at cruise. Separated flow effects cause cruise performance penalties, and can often restrict vehicle operating conditions.

Objectives

The objectives of the meeting are to: • Establish baseline for current and anticipated air and sea vehicle issues regarding separated flow effects • Establish baseline of current capability to predict separated flow effects and to measure separated flow phenomena that are relevant to air- and sea-vehicle needs • Identify key areas requiring further research and development Emphasis is placed on separated flows relevant to operation of advanced air and sea military vehicles. Contributions can include systems and fundamental studies as well as numerical and experimental investigations.

Topics

Separated flow aerodynamics and hydrodynamics. Current and anticipated air and sea vehicle issues regarding separated flow effects. Current capabilities in experimental and numerical investigations of separated flows.
