== Boundary Layer for Flow Past a Wedge ==
The Blausius boundary layer velocity solution is a special case of a larger class of problems for [http://en.wikipedia.org/wiki/Blasius_boundary_layer; flow over a wedge], as shown in the following figure. The angle represents the wedge angle.

The general solution is called the Falkner-Skan boundary layer solution, which starts with a recognition that the free-stream velocity will accelerate for non-zero values of :
where is a characteristic length and ''m'' is a dimensionless constant that depends on :
The condition ''m = 0'' gives zero flow acceleration corresponding to the Blausius solution for flat-plate flow.
We then define a similarity variable that combines the local streamwise and cross-flow coordinates ''x'' and ''y'' (defined relative to the surface of the wedge):
