WebAn experimental study of primary breakup of turbulent liquids is described, emphasizing liquid/gas density ratios less than 500 where aerodynamics effects are important. The experiments involved multiphase mixing layers along round water jets (3.6 and 6.2 mm dia.) injected at various velocities into still helium, air and Freon 12 at pressures of 1 and 2 … WebApr 5, 2024 · (a) Droplet stream generated by the jet breakup under a perturbation of 6 kHz, where the jet radius without perturbation was calibrated as 127 µm and the flow rate was …

Experiments and numerical simulations demonstrate that the jet breakup and the subsequent droplet merging are ... WebMany industrially relevant emulsification devices are of the high-energy type, where drop deformation and subsequent breakup, take place due to intense turbulent fluid–drop interactions. This includes high-pressure homogenizers as well as rotor-stator mixers (also known as high-shear mixers) of various designs. The stress acting on a drop in a turbulent … 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 … See more The Plateau–Rayleigh instability, often just called the Rayleigh instability, explains why and how a falling stream of fluid breaks up into smaller packets with the same volume but less surface area. It is related to the Rayleigh–Taylor instability See more Water dripping from a faucet/tap A special case of this is the formation of small droplets when water is dripping from a faucet/tap. When a … See more • Plateau–Rayleigh Instability – a 3D lattice kinetic Monte Carlo simulation • Savart–Plateau–Rayleigh instability of a water column – Adaptive numerical simulation See more The explanation of this instability begins with the existence of tiny perturbations in the stream.
