Rankine Vortex

The Rankine vortex model: solid-body rotation inside radius R, irrotational flow outside. Click to add/move vortices.

v(r) = Ωr for r ≤ R

v(r) = ΩR²/r for r > R

Core Radius: 60px Strength: 80 Mode: Particles: 120

Click canvas to move primary vortex. Multiple vortices interact via superposition.
