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, 201... Full description

520 |a 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 with a suspension of droplets of an immiscible liquid. Based on a set of direct numerical simulations, the authors provide new insights on how turbulence affects the motion of the droplets, their shape and size; then in turn how the droplets alter the flow including effects of interfacial surface energy on the kinetic energy of the flow. Continuing advances in methods for large-scale simulations with better control of mass conservation, adaptive refinement and the ability to handle large density and viscosity ratios are making it feasible to explore more deeply the dynamics of turbulent liquid-liquid or liquid-gas disperse two-phase flow. The work of DF is significant in terms of the large number of droplets, 3130 initially, and resolution (D = 32⇋x) which makes meaningful statistical analysis possible. Many questions remain open for both droplet and bubble flows. One of these is the evolution of the droplet spectrum and the observation by Lasheras & Hopfmger (2000) that in a stationary flow a balance between breakup and coalescence results in an equilibrium size distribution independent of the initial spectrum. The experiments by Bateson & Aliseda (2012) address this for small droplets (D œ́Þ⇋ʺK) at very low volume fractions for conditions relevant to atmospheric clouds. It remains to be seen what happens in more general engineering (and culinary) contexts.
