Rayleigh–plateau hydrodynamic instability
WebSep 10, 2008 · Droplets coalescing at a planar fluid-fluid interface are studied in detail in the Stokes regime with high speed photography. Attention is paid to the expansion of the interfacial bridge, formed between the droplet and interface, as it expands during the process. We report a hydrodynamic instability at the rim of the interfacial bridge. As the … WebA soft cylindrical interface endowed with surface tension can be unstable to wavy undulations. This is known as the Plateau–Rayleigh instability (PRI) and for solids the instability is governed by the competition between elasticity and capillarity. A dynamic stability analysis is performed for the cases of a soft (i) cylinder and (ii ...

WebJun 12, 2015 · Here we revisit the Plateau-Rayleigh instability of a liquid coating a fibre by varying the hydrodynamic boundary condition at the fibre-liquid interface, from no slip to slip. Although the wavelength is not sensitive to the solid-liquid interface, we find that the growth rate of the undulations strongly depends on the hydrodynamic boundary condition. WebI. Introduction. The convective instability of a layer of Boussinesq fluids heated uniformly from below is one of the simplest examples of hydrodynamic instability. This phenomenon, known as Rayleigh-Benard (R-B) convection, shows a clear transi-tion from the uniform conduction solution, to a steady motion varying periodically in space.
