Experimental statistics of droplet trajectory and air flow during aerodynamic fragmentation of liquid drops

Investigation of water droplets, kerosene and ethanol deformation in the air

“…It has been identified in experiments [8][9][10] that the probability of liquid droplet breakup is high at Weber's numbers more than 10. Generally, value of We lim = 10 is considered as a maximum permissible one when the solidity preservation of liquids droplets during motion in gas area is possible.…”

“…Videogams of experiments [7][8][9] allows carrying the inference that the velocities of droplets movement may significantly influence on the droplets form and the nature of their deformation. High-velocity video registration of droplets movement in gas areas (with various properties, sizes and velocities) is of interest.…”

“…It will allow establishing the most typical forms of droplets to use at corresponding processes simulation and transition times from one form to another during movement. It is understandable that, it is necessary to investigate the regularities of deformation not only within the first, but also the group of the subsequent "strain cycles" to extend the possible supplements (for example, perspective gas-and vapor-droplet technologies [9,10]) of received results in contrast to the experiments [3][4][5][6].…”

The Review of Ignition and Combustion Processes for Water-Coal Fuels

“…The non-Newton fluid theory was used to describe the viscosity effects for the water-coal fuel. The comparison of this simulation results with experimental data [51] shows that proposed at [50] approach allows having enough good correlation in case of right choice of the rheological properties of the slurry.…”

Droplets in turbulence: a new perspective

“…Atomization of a liquid jet with a coaxial gas stream will rapidly generate a fine spray of droplets with a range of sizes depending on the Reynolds number of the flow and the Weber number (Lasheras & Hopfinger 2000). Individual droplets in an air flow can undergo oscillations in shape and may fragment via different modes, again depending on We and γ (Flock et al 2012). These features are included in engineering models and correlations but there is still limited information from first-principles direct numerical simulations.…”
