# Joukowski Airfoil: Aerodynamic Properties

Requires a Wolfram Notebook System

Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.

The surface pressure distribution for potential flow over one of the Joukowski family of airfoils is presented in the format conventional for airfoil aerodynamics; the characteristic length is the chord of the airfoil and pressure is presented as a dimensionless pressure coefficient. The shape of the airfoil is included as an insert. Slider controls are provided for the shape of the airfoil and the angle of attack.

## Snapshots

## Details

Details of potential flow over a Joukowski airfoil and the background material needed to understand this problem are discussed in a collection of CDF files available at [1].

Snapshot 1: thick symmetric airfoil at moderate angle of attack

Snapshot 2: thin cambered airfoil at moderate angle of attack

Snapshot 3: thick cambered airfoil at high angle of attack; potential flow gives no information about when separation occurs
