Question Analytical relation for the length of the wake behind a cylinder in an external flow

Hello all,

Does somebody know if there is an analytical relation to calculate the length of the wake formed behind a cylinder in a turbulent external flow of air? There are analytical equations to calculate the pressure field and velocity (and the lift and the drag) around the surface of the cylinder, but I haven't been able to find anything for the length of the wake.

An empirical relation would be okay as well. If an empirical relation is being proposed, please specify the Reynolds numbers for which the relation would be valid.
