Computation of the rise or fall of a drop through a suspending liquid with no mass transfer: Axisymmetric, transitional and complex regimes
… with the drop’s center-of-mass, leaving a helical wake. Transient development of the helical wake and its long-time structure are analysed in detail, and mechanisms leading to the rotational motion are discussed. The flow associated with the wake is shown to have a special point …

An Improved Prescribed Wake Analysis for Wind Turbine Rotors
… blades are presented. The pitch of the ensuing helical wake is found to be modeled well by the reciprocal of the rotor tip speed ratio. The radial locations of the tip vortices stay relatively constant at 97% radius. The exception to this is when the rotor is operating under a high thrust …
