Potential Flow Around a Sphere
The potential (inviscid) flow around a sphere is equivalent to the superposition of a 3D doublet and a free stream, which reduces to the simple analytic equation:
Cp = 1 - 9/4 cos2(theta)
Cp is the Pressure Coefficent
theta is the angle measured perpendicular to the flow direction
Surface Pressure Coefficient Contours.
Pressure Coefficient comparison between potential flow theory for a sphere and computation.
Notice the excellent agreement between the computation and the theory.
