Flow Past a Wedge (Falkner/Skan)

The inviscid solution is of the form U (x) = Cxm. The governing equation for the self-similar solution for the stream function reads

F"’ + FF” + в(1 – F’2) = 0 (8.85)

where в = mm is the wedge angle, and with boundary conditions

• at n = 0: F = F’ = 0,

• as n F’ ^ 1.

For more on this, we refer to Hartee numerical analysis and Stewartson analysis.

Special cases:

• Flat plate: m = 0, в = 0.

• Stagnation point: m = 1, в = 1.

When в < 0 (m < 0), separation occurs.
