Vortexes are physical phenomena found throughout nature, including tornados and air turbulence, which is a vortex buildup process (Figure 1). Investigators have realized that turbulence is not a ...

The Vortex Particle Method (VPM), a meshless vortex flow simulation approach, is gaining traction for its efficient simulation of unsteady vortex wakes evolution that is shed by aircrafts, rotors and ...

SIAM Journal on Numerical Analysis, Vol. 24, No. 3 (Jun., 1987), pp. 538-582 (45 pages) We prove the convergence of a large class of vortex methods for two-dimensional incompressible, inviscid flows ...

This is a preview. Log in through your library . Abstract We consider incompressible 2d Navier-Stokes equations in the whole plane with external nonconservative forces fields. The initial data and ...

Helicopter safety researchers are to undertake formal analysis of the hazardous vortex ring phenomenon and the effectiveness of an alternative recovery and escape technique. The vortex ring state is ...

In a paper recently published in the journal Ocean Engineering, researchers employed a free-surface vortex method for crude oil recovery, while studying its flow process in a vortex by carrying out ...

In an early sign of the winter weather that's coming, the dreaded polar vortex is making news yet again. The polar vortex is "ramping up from its summer slumber," said meteorologist Judah Cohen in an ...
