Numerical Simulation of Gas-liquid Two-phase Flow in Emergency Rescue Drainage Pump Based on MUSIG Model [PDF]
Journal of Applied Fluid MechanicsTo investigate the gas-liquid two-phase flow characteristics in an emergency rescue drainage pump, the MUSIG model was adopted to analyze the effect of the gas phase on the internal flow characteristics of the pump.

Guiding-center dynamics of vortex dipoles in Bose-Einstein condensates
, 2011 A quantized vortex dipole is the simplest vortex molecule, comprising two counter-circulating vortex lines in a superfluid. Although vortex dipoles are endemic in two-dimensional superfluids, the precise details of their dynamics have remained largely ...

Motion of vortices in inhomogeneous Bose-Einstein condensates
, 2018 We derive a general and exact equation of motion for a quantised vortex in an inhomogeneous two-dimensional Bose-Einstein condensate. This equation expresses the velocity of a vortex as a sum of local ambient density and phase gradients in the vicinity ...

SIAM Journal on Numerical Analysis, 1985 Error estimates for fully discretized two- and three-dimensional vortex methods for Euler's equations are given. An elementary proof of the consistency result by \textit{G. H. Cottet} [Thèse de 3ième cycle, to appear], together with its three-dimensional analogue is presented. Following the convergence theory of \textit{J. T.

Statistical two-vortex equilibrium and vortex merger [PDF]
Physical Review E, 1996 Two-vortex solutions from the mean field equations respecting all conservation laws of the Euler equations in two dimensions are calculated in a unit disk. These states are compared to symmetric and off-center single-vortex solutions. A thermodynamic stability analysis is used to determine their stability and a critical separation for stable two-vortex

Suppression of Kelvon-induced decay of quantized vortices in oblate Bose-Einstein Condensates
, 2011 We study the Kelvin mode excitations on a vortex line in a three-dimensional trapped Bose-Einstein condensate at finite temperature. Our stochastic Gross-Pitaevskii simulations show that the activation of these modes can be suppressed by tightening the ...

The Steady Motion of a Symmetric, Finite Core Size, Counterrotating Vortex Pair [PDF]
, 1994 The steady motion of a symmetric, finite core size, counterrotating vortex pair is characterized by circulation r, a velocity V, and a spacing 2x_∞. In the classical limit of a point vortex, the normalized velocity, vx_∞/r, is 1/(4π).
