Generation of Vortex Ring with Maximum Circulation.

Circulation Generation and Vortex Ring Formation by Conic Nozzles

Vortex rings are one of the fundamental flow structures in nature. In this paper, the generation of circulation and vortex rings by a vortex generator with a static converging conic nozzle exit is studied numerically. Conic nozzles can manipulate circulation and other flow invariants by accelerating the flow, increasing the Reynolds number, and by establishing a two-dimensional flow at the exit...

Sound generation by a vortex ring collision

Vortex ring

By rigorous mathematical method, we construct traveling wave solutions with a stationary or traveling vortex ring to the Gross-Pitaevskii equation iût = ε 2 4 û + ( Ṽ − |û| ) û, û ∈ H(R), where the unknown function û is defined as û : R × R → C, ε is a small positive parameter and Ṽ is a smooth potential.

Evolution of a Curved Vortex Filament into a Vortex Ring

Hydrodynamic Investigation of Free-Surface Turbulent Vortex Flows with Strong Circulation in a Vortex Chamber

The results obtained from analytical, numerical and experimental modelling of free-surface vortex flows are presented. Vortex flow in an open channel flow chamber is simulated using the ANSYS CFX steady Eulerian-Eulerian multiphase flow model with various turbulence closure methods. The water surface and tangential velocity profile are also modelled using the Vatistas ( 2) vortex model. These p...
