pysces.joukowski_foil(xcenter=-0.1, ycenter=0.1, a=1, numpoints=32)

Return a Joukowski foil Body.

The foil has its trailing edge at (2a,0). The foil has a total of numpoints along the boundary. Refer to chapter 4 of [R1] for details.

Parameters:

xcenter, ycenter : float

(xcenter,ycenter) is the center of the Joukowski preimage circle. xcenter should be negative and small; its magnitude determines the bluffness of the foil. ycenter should be small; it determines the magnitude of the camber (positive gives upward camber, and negative gives downward camber).

a : float

radius of the Joukowski preimage circle

numpoints : int

number of points along the boundary
