A fully adaptive front tracking method for the simulation of two phase flows

An improved Front-Tracking technique for the simulation of mass transfer in dense bubbly flows

“…Of course, FT also has some drawbacks, most notably the fact that the volume of the dispersed phases is not intrinsically conserved (Van Sint Annaland et al, 2006;Pivello et al, 2013). Changes in the volume enclosed by the mesh may accumulate significantly during a simulation (Fig.…”

Experimental studies on the shape and motion of air bubbles in viscous liquids

“…It has guiding significance for in-depth study of bubble dynamics in gas-liquid two-phase flow to solve many engineering problems. Researches on the bubble dynamics have been conducted for decades, and many achievements have been accomplished by using theoretical analysis [4][5][6][7][8], experimental measurement [9][10][11][12][13][14] and numerical simulation [15][16][17][18][19][20], showing that the interactions between gas and liquid, i.e. viscous force, gravity, surface tension, and inertial force, mainly dominate the behavior of bubble dynamics.…”

Dynamics of an initially spherical bubble rising in quiescent liquid

“…These studies typically used one or two sets of Eötvös number and Galilei number. There have also been several studies in which the computational techniques needed to resolve this complicated problem have been perfected [7][8][9]11,12,16 . Furthermore, ref.…”
