In Fluid Mechanics, the Lamb-Oseen vortex models a line vortex that decays due to viscosity.
Additional recommended knowledge
The mathematical model for the velocity in the θ direction in the Lamb-Oseen vortex is:
r = radius rc = Core radius of vortex Γ = Circulation contained in the vortex
An alternative definition is to use the peak tangential velocity of the vortex rather than the total circulation
where α = 1.26 as used in Devenport et al in a 1996 Journal of Fluid Mechanics paper (vol 312, pp67-106).
