== Boundary Layer for Flow Past a Wedge ==

The Blausius boundary layer velocity solution is a special case of a larger class of problems for flow over a wedge, as shown in the following figure. The angle <math>\beta \pi</math> 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 <math>\beta</math>:

<math>u_{e}(x)= U_{0} \left( x/L \right) ^{m}</math>

where <math> L </math> is a characteristic length and ''m'' is a dimensionless constant that depends on <math>\beta</math>

<math>
{\beta} = \frac{2m}{m + 1}
</math>

 The condition ''m = 0'' gives zero flow acceleration corresponding to the Blausius solution for flat-plate flow.
