The bubbly flow is encountered in many industrial processes. Numerical efforts dedicated to
the explanation of the bubbly flow physics have never been overemphasized. Based on the …

Bubbles have very important applications in many fields such as shipbuilding engineering,
ocean engineering, mechanical engineering, environmental engineering, chemical …

Small amounts of surfactant can drastically change bubble behavior. For example, a bubble
in aqueous surfactant solution rises much slower than one in purified water. This …

Photobioreactor (PBR) is the most critical equipment for microalgal photosynthetic fixation of
CO 2. It provides suitable environmental conditions, such as CO 2, light and nutrients, for …

Bubbly flow is a prototypical two-phase flow problem. The dynamic behavior of bubbles
within a reactor is intrinsically linked to their transport, distribution, and mass transfer, all of …

In the present study, we preformed a two-dimensional numerical simulation of the motion
and coalescence of bubble pairs rising in the stationary liquid pool, using the moving …

The goal of this study is to present new experimental data on the effect of the bubble
approach velocity and liquid viscosity on pairwise bubble coalescence. Measurements were …

In the present study, the motion and interaction of a bubble pair rising in a stationary liquid
are simulated in two dimensions using the volume of fluid method (VOF) in the open-source …

Bubble coalescence experiments have been performed using a sliding bubble apparatus, in
which mm-sized bubbles in an aqueous electrolyte solution without added surfactant rose …

This paper presents a numerical study of buoyancy-driven motion of single and multiple
bubbles by means of the conservative level-set method. First, an extensive study of the …
