Finite time breakup of viscous filaments
We analyze a model equation for the evolution of surface tension driven instabilities on a viscous jet. For a general class of initial data, it is proved that the jet breaks in finite time.
متن کاملBreakup of Liquid Jets
For fundamental analysis of the transport of mass or heat in a dispersed system, accurate knowledge of behavior of jet is prerequisite. For generation of high interfacial area breaking of liquid jet in to small droplet is necessary. Liquid jet breakup is a complex phenomenon and dependent on many factors like velocity of jet, pressure difference, geometry of nozzle, temperature of both fluid, p...
متن کامل2 dimensional finite stochastic breakup model of biomass particle breakup.
Due to the high content of cellulose, hemicellulose and lignin, the anisotropy of biomass particle in spatial structure induces the difference of mechanical properties in different directions. In this paper, based on the finite stochastic breakup model and anisotropy of biomass particles, 2-dimensional finite stochastic breakup model (2D-FSBM) of biomass particle was proposed, and the breakup p...
متن کاملPlethora of transitions during breakup of liquid filaments.
Thinning and breakup of liquid filaments are central to dripping of leaky faucets, inkjet drop formation, and raindrop fragmentation. As the filament radius decreases, curvature and capillary pressure, both inversely proportional to radius, increase and fluid is expelled with increasing velocity from the neck. As the neck radius vanishes, the governing equations become singular and the filament...
متن کاملOn the breakup of viscous liquid threads
A one-dimensional model evolution equation is used to describe the nonlinear dynamics that can lead to the breakup of a cylindrical thread of Newtonian uid when capillary forces drive the motion. The model is derived from the Stokes equations by use of rational asymptotic expansions and under a slender jet approximation. The equations are solved numerically and the jet radius is found to vanish...
