Web13 de out. de 2011 · The breakup process of a low speed capillary liquid jet is computationally investigated for different Ohnesorge numbers (Z), wave numbers (K), and disturbance amplitudes (ζo). An implicit finite difference scheme has been developed to solve the governing equations of a viscous liquid jet. The results predict the evolution … Web7 de nov. de 2013 · We study axisymmetric breakup and drop formation of a liquid thread confined in a cylindrical tube by using a long wave model. The limit with large viscosity contrast is investigated, consisting of a highly viscous core and a less viscous annulus.
Web8 de out. de 2024 · We show for the first time that only one similarity solution that describes the break-up of viscous liquid threads is linearly stable, while other similarity solutions … Web8 de out. de 2024 · Abstract. In this paper we compute the linear stability of similarity solutions of the breakup of viscous liquid threads, in which the viscosity and inertia of the liquid are in balance with the surface tension. The stability of the similarity solution is determined using numerical continuation to find the dominant eigenvalues.
WebIt is shown that at the level of the cross-over between these two regimes it is more probable to produce monodisperse droplets because fluctuation-dominated pinch-off may allow the unique situation where satellite drop formation can be inhibited.

WebHistory. The Plateau–Rayleigh instability is named for Joseph Plateau and Lord Rayleigh.In 1873, Plateau found experimentally that a vertically falling stream of water will break up into drops if its length is greater than about 3.13 to 3.18 times its diameter, which he noted is close to π. Later, Rayleigh showed theoretically that a vertically falling column of non …
