Physical Review Fluids publishes a collection of papers associated with the invited talks presented at the 69th Annual Meeting of the APS Division of Fluid Dynamics.
Prior work on curvature capillary attraction for colloids on fluid interfaces is extended, and the concept of curvature capillary repulsion is introduced.
The mechanisms that underlie the interactions between the inner and outer regions of wall-bounded turbulence are considered, and their effect on the near-wall turbulence intensity is discussed.
We investigate effects of stratification on the hydrodynamics of settling particles, rising drops, and small organism motion. Density stratification leads to enhanced clustering in a suspension of particles/drops and affects the flow field, energy expenditure, and detectability of small organisms.
Low-dimensional models of experimental and simulation data for a complex supersonic jet are fused to reconstruct time-dependent coefficients. Data fusion techniques use the strengths of experimental statistical ensembles and the time resolution of large-eddy simulation to provide a more complete view of the flow.
Some semi-aquatic insects, such as water striders and springtails, can jump off the water surface by exploiting the interfacial tension to escape from predators. We present a theoretical framework to analyze and predict the jumping of those insects.
The paper illustrates the potential of advanced optical metrology combined with DNS for the study of near-wall turbulence including the critical case of a turbulent boundary layer in a mild adverse pressure gradient. Insights obtained point towards significant improvements in turbulence modelling.
Professor Stone discusses some aspects of his research group’s recent studies related to multiphase flows and the flows of complex fluids for which he received the APS Fluid Dynamics Prize.
