## Summary

This course will provide the fluid dynamic background to understand how air flows around two- and three-dimensional wings and bodies and to understand and calculate the aerodynamics forces and moments acting on the objects as a result of the air flow.

## Content

INTRODUCTION:
- Basic concepts
- Definitions
- Fundamental equations
- Potential flow
- Infinite wing theory
- Finite wing theory
VISCOUS INCOMPRESSIBLE FLOWS
- Drag
- Boundary layes and flow separation
- Flow control

## Learning Outcomes

By the end of the course, the student must be able to:

• Describe the physical behaviour of a flow in scientific terms, AH1
• Link flow behaviour with non-dimensional parameters (e.g. Reynolds and Mach numbers), AH2
• Describe the physical differences between laminar and turbulent flows, AH4
• Describe in detail the physical phenomena associated with the interaction of a flow with a solid wall (as a function of its characteristics, e.g. roughness), AH5
• Describe flow in simple geometries, such as over a flat plate, in a tube, or around a sphere or airfoil, AH9
• Work out / Determine the flight characteristics from a wing shape and chose a wing shape to provide the desired flight characteristics, AH10
• Describe 3D effects resulting, for example, from a finite wing span or behind a blunt body, AH11
• Solve analytically or numerically the potential flow around an airfoil, AH19

## Transversal skills
