OVERVIEW
Concentrated vortex flows are characterized by coherent vorticity created from the highly swept edges of a lifting surface on an aircraft. This coherent vorticity can be exploited to improve aerodynamic performance, and such use of these flows is referred to as vortex-flow aerodynamics. Key technical topics for the Vortex Flow Aerodynamics course include concentrated vortex flow physics, aircraft applications of concentrated vortex flows, CFD methodologies for simulating concentrated vortex flows, a state-of-the-art assessment for prediction of concentrated vortex flow aerodynamics, and opportunities to advance the understanding of and simulation confidence for concentrated vortex flow aerodynamics. The course will touch upon an approach that merges a physics-based perspective of the concentrated vortex flows with a systems engineering viewpoint of the air vehicle.

LEARNING OBJECTIVES

• Grasp the uses of concentrated vortex flows for aircraft aerodynamics
• Comprehend the fundamental flow physics and properties of concentrated vortex flows
• Discern the strengths and weaknesses for simulation of concentrated vortex flows from a hierarchy of computational fluid dynamic techniques
• Become aware of opportunities for new research to improve the ability to use concentrated vortex flows for vehicle aerodynamics

AUDIENCE
This course is intended for holders of a BS degree in aeronautical/aerospace engineering who have had coverage of basic aerodynamic subjects but who have not had any significant exposure to vortex flow aerodynamics. These audience members might be new graduates or experienced engineers who want to learn about the basic role concentrated vortex flows play in aircraft aerodynamic performance. Course participants should be able to perform basic Computational Fluid Dynamics simulations and/or basic wind tunnel experimentation pertinent to aircraft aerodynamics, although these topics will be reviewed within the course. Audience members with added interest in maneuver aerodynamics and separated flow management can use this course to prepare for those more advanced topics.
