Rise regimes of freely rising droplets with a moderate viscosity ratio
Pengyu Shi, Dirk Lucas, Jie Zhang +2
The dynamics of buoyant droplets rising freely in a large body of an immiscible liquid is investigated numerically for a moderate drop-to-fluid viscosity ratio . We focus o…
A pair of oblate bubbles rising in-line: a linear stability analysis
Wei-Qiang Liu, Jian-Ming Jiang, Jie Zhang
The stability of two bubbles rising initially in-line through a viscous liquid is revisited using a global linear stability analysis formulated within an Arbitrary Lagrangian-Euler…
Applying contact angles based on a continuously moving contact line in 2D VOF simulations
Tianyang Han, Jieyun Pan, Chongsen Huang +4
A height-function-based numerical approach is developed for enforcing contact angles on flat and curved solid surfaces within two-dimensional volume-of-fluid simulations. This meth…
Wake instability past a sphere settling in a strongly stratified flow
Chang-Fan Mo, Matthieu J. Mercier, Jacques Magnaudet +1
The wake of a body moving across the isopycnals of a strongly stratified fluid is characterized by the presence of an intense jet which, under certain circumstances, may become uns…
A sharp and conservative method for modeling interfacial flows with insoluble surfactants in the framework of a geometric volume-of-fluid approach
Zhong-Han Xue, Jacques Magnaudet, Jie Zhang
Insoluble surfactants adsorbed at liquid-liquid or gas-liquid interfaces alter interfacial tension, leading to variations in the normal stress jump and generating tangential Marang…
Lateral migration and bouncing of a deformable bubble rising near a vertical wall. Part 2. Highly inertial regimes
Pengyu Shi, Jie Zhang, Jacques Magnaudet
The fate of deformable buoyancy-driven bubbles rising near a vertical wall under highly inertial conditions is investigated numerically. In the absence of path instability, simulat…
Path of a pair of deformable bubbles rising initially in line and close to a vertical wall
Haochen Huang, Pengyu Shi, Nina Elkina +2
It is known that in an unbounded fluid, the inline configuration of a freely rising bubble pair is often unstable with respect to lateral disturbances. This work numerically examin…
Lateral migration and bouncing of a deformable bubble rising near a vertical wall. Part 1. Moderately inertial regimes
Pengyu Shi, Jie Zhang, Jacques Magnaudet
The buoyancy-driven motion of a deformable bubble rising near a vertical hydrophilic wall is studied numerically. We focus on moderately inertial regimes in which the bubble underg…
