Particle - laden tubeless siphon
A tubeless siphon was created by sucking a 1% aqueous Polyox† solution laden with particles from a beaker into a cylinder by moving a piston. The piston speed and particle concentration were varied. At very high rates of withdrawal, all the liquid could be removed before the siphon broke. In this case, the beaker was completely cleaned without a trace of liquid. The addition of small concentrat...
متن کاملNanoparticle - laden tubeless and open siphons †
Tubeless and open siphons operate without conduits, in the open, supported only by extensional stresses. Here, we demonstrate that the addition of silica nanoparticles in modest concentrations (on the order of 1% by weight) to an aqueous Poly(ethylene oxide) (PEO) solution of a moderately low concentration (0.5% by weight) has a dramatic effect on the power of the siphon as well as on the abili...

متن کاملGranular and Particle-Laden Flows
This research programme at the Newton Institute was devoted to improving the understanding and mathematical modelling of granular and particle-laden fluid systems as they arise in nature, in the laboratory and in industry. Geophysical examples of granular and particle-laden flows include rock avalanches, debris flows, mud flows and turbulent boundary layers with suspended particles, such as vol...
متن کاملBuckling of particle-laden interfaces.
In this paper, we investigate the buckling of an oil-water interface populated by micron-sized latex particles using a Langmuir trough. In this work, we extend results of buckling of particle-laden interfaces from the millimeter down to the submicron range while investigating the effect of a different capillary length on the resulting wavelength. The experimental data is compared to the existin...
