Droplets in turbulence: a new perspective
Stirring olive oil and vinegar to make salad dressing creates an emulsion of vinegar droplets in oil. More vigorous stirring gives smaller droplets, while if left to sit the droplets will begin to coalesce and the two fluids will separate. In this vein, Dodd & Ferrante (J. Fluid Mech., vol. 806, 2016, pp. 356–412) present a new analysis of how homogeneous turbulence in a carrier fluid interacts...
متن کاملRapid growth of cloud droplets by turbulence.
Assuming perfect collision efficiency, we demonstrate that turbulence can initiate and sustain the rapid growth of very small water droplets in air even when these droplets are too small to cluster, and even without having to take gravity and small-scale intermittency into account. This is because the range of local Stokes numbers of identical droplets in the turbulent flow field is broad enoug...
متن کاملFinite temperature Functional RG, droplets and decaying Burgers Turbulence
– The functional RG (FRG) approach to pinning of d-dimensional manifolds is reexamined at any temperature T . A simple relation between the coupling function R(u) and a physical observable is shown in any d. In d = 0 its beta function is displayed to a high order, ambiguities resolved; for random field disorder (Sinai model) we obtain exactly the T = 0 fixed point R(u) as well as its thermal bo...
متن کاملTurbulence modification by dispersion of large deformable droplets
Dispersion of large deformable droplets in turbulent channel flow is investigated: the fluids are considered of same density and viscosity for a broad range of plausible values of surface tension. Droplets much larger than the Kolmogorov length scale are released in a channel flow; the turbulent flow is computed with pseudo-spectral Direct Numerical Simulations (DNS), while phase interactions a...
متن کاملGlow Clustering
We introduce Glow Clustering, a clustering technique inspired by the physics of light and the images of spiral galaxies. We discuss the genesis, design, and implementation of Glow Clustering. We evaluate Glow Clustering on test datasets and a well-known standard dataset. Finally, we attempt to describe the characteristics of Glow Clustering, giving some insight into the context of use where Glo...
