Direct Numerical Simulations of Gas-Liquid Multiphase Flows
TL;DR: In this paper, a review of the state-of-the-art numerical methods used for direct numerical simulations of multiphase flows, with a particular emphasis on methods that use the so-called "one-field" formulation of the governing equations, is presented.

Dynamics of an initially spherical bubble rising in quiescent liquid
TL;DR: It is reported that the dynamics is fully three-dimensional, and provide a broad canvas of behaviour patterns, and a perfect correlation between large shape asymmetry and path instability is established.

3-D turbulence structure and phase distribution measurements in bubbly two-phase flows
TL;DR: In this article, the authors measured important flow quantities such as local void fraction, liquid velocity and the Reynolds stresses using both single-sensor and three-Sensor hot-film anemometer probes, and found that the observed wall peaking and coring phenomena in up and down flows could be predicted by considering the turbulence structure of the continuous phase and lateral lift force acting on the dispersed phase.
