Statistical mechanics of bubbly liquids [PDF]
, 1996 The dynamics of bubbles at high Reynolds numbers is studied from the viewpoint of statistical mechanics. Individual bubbles are treated as dipoles in potential flow.

Eulerian-Lagrangian method for simulation of cloud cavitation [PDF]
, 2017 We present a coupled Eulerian-Lagrangian method to simulate cloud cavitation in a compressible liquid. The method is designed to capture the strong, volumetric oscillations of each bubble and the bubble-scattered acoustics.

On the characteristics of the equations of motion for a bubbly flow and the related problem of critical flow [PDF]
, 1976 For the study of transients in gas-liquid flows, the equations of the so-called separated flow model are inadequate, because they possess, in the general case where gas and liquid move at different velocities, complex characteristics.

Bubbly and Buoyant Particle-Laden Turbulent Flows [PDF]
, 2020 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 flows contain suspensions of dispersed bubbles and light ...

Some Observations of Flow Patterns and Statistical Properties of Three Component Flows [PDF]
, 1988 Vertical air-water flows, solids-water flows and three component air-solids-water flows were investigated in a Three Component Flow Facility. Visual observations of the flow patterns show that three component flows undergo transition and can exhibit ...
