🌀 Wingtip Vortex Wake: Circulation, Lamb-Oseen Core Growth and Descent (2D rear view)

Rear view of the pair of counter-rotating vortices shed by an aircraft wing. Set mass, span, speed, air density, core size, eddy viscosity and wake age, and watch circulation, vortex spacing, core radius, swirl speed and the descent of the pair. Standard aerodynamics, with four in-page numerical checks.
