Bubbly and buoyant particle–laden turbulent flows
Fluid turbulence is commonly associated with stronger drag, greater heat transfer, and more
efficient mixing than in laminar flows. In many natural and industrial settings, turbulent liquid …

Hydrodynamic interactions among bubbles, drops, and particles in non-Newtonian liquids
The understanding of hydrodynamic forces around particles, drops, or bubbles moving in
Newtonian liquids is modestly mature. It is possible to obtain predictions of the attractive …
