Viscous entrainment from a nozzle: singular liquid spouts.
نویسنده
چکیده
We analyze a long-wavelength model of viscous entrainment from a nozzle and show that, when appropriate large-scale boundary conditions are imposed, the entrainment transition can become continuous. As the entrainment threshold is approached from above, the entrained steady-state spout becomes vanishingly thin compared to the nozzle radius and takes the form of a thin tendril emerging from a base profile whose tip is perfectly conical.

Air entrainment by contact lines of a solid plate plunged into a viscous fluid.
The entrainment of air by advancing contact lines is studied by plunging a solid plate into a very viscous liquid. Above a threshold velocity, we observe the formation of an extended air film, typically 10 microns thick, which subsequently decays into air bubbles. Exploring a large range of viscous liquids, we find an unexpectedly weak dependence of entrainment speed on liquid viscosity, pointi...
متن کاملEntrainment Characteristics of Turbulent Round Gas Jets Submerged in Water
The entrainment process in two-phase buoyant jets differs significantly from their singlephase counterparts, and is not well understood. Entrainment models developed for singlephase flow are often used in two-phase jetting simulations, albeit with limited success. In this work, Particle Image Velocimetry (PIV) and shadowgraph flow visualization experiments have been conducted on submerged round...
متن کاملHollow-cone Spray of Viscous Liquid in High-pressure Gas Environment - Experimental Investigation for the Application of New Liquid Fuels to Gas-turbine -
Abstract Experimental investigations were performed on the hollow-cone spray of viscous liquids in high-pressure gas environment, aiming to obtain fundamental knowledge which was indispensable to survey the applicability of non-conventional new liquid fuels for the gas-turbine power-plant. Test liquid employed were water, diesel fuel, palm methyl ester (PME) and silicone-oil #10. The ambient ga...
متن کاملFree surface electrospinning from a wire electrode
Electrostatic jetting from a free liquid surface offers an alternative to conventional electrospinning in which jets are emitted from spinnerets. In this work we analyze a system in which a wire electrode is swept (in a rotary motion) through a bath containing a polymeric solution in contact with a high voltage, resulting in entrainment of the fluid, the formation of liquid droplets on the wire...
متن کاملExperimental Study on Performance of Two-phase Ejector Refrigeration Cycle System with Two-throat Nozzle
The two-phase ejector refrigeration cycle (TPERC) system with a two-throat nozzle ejector was investigated experimentally, and the entrainment ratio of the ejector and the COP of the system were compared with those of the ejector with Laval nozzle and its TPERC system respectively. The experimental results indicate that under the working condition of the evaporating/condensing temperatures 1°C/...
