Area: Computes the overlap area for the partial Jensen wake.
Description
The partial Jensen wake model requires the overlap area of the rotor disc at the downwind location with the wake disc. This function computes it.
Usage
Area(a, b, d)
Value
Area returns covered area in square meters.
Arguments
a
must be a single value. Provide the radius of the first circle in meters.
b
must be a single value. Provide the radius of the second circle in meters.
d
must be a single value. Provide the distance between the two circles' centers.

Details
If a turbine is downwind another turbine, the wake cone of that upwind turbine may only partially cover the rotor disc of the second turbine. For the partial wake model it is necessary to compute the covered area.
