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 …

The mechanisms of bubble formation and the dynamics of bubble growth in common
magmas have been investigated. Experimental and theoretical data suggest that the levels …

The shapes and terminal velocities of bubbles rising in viscous liquids have been
determined. For Morton numbers (M) greater than 4× 10− 3 the drag coefficient and …

抄録 Simple but reliable correlations for a drag coefficient, CD, of single bubbles under a
wide range of fluid properties, bubble diameter and acceleration of gravity were developed …

Works on computational bubble dynamics having carried out since 1990 in Laboratory of
Multiphase Flow Engineering in Kobe University are reviewed in this report. The topics …

The formation of gas bubbles and their subsequent rise due to buoyancy are very important
fundamental phenomena that contribute significantly to the hydrodynamics in gas− liquid …

A simple coupled Volume of Fluid (VOF) with Level Set (LS) method (S-CLSVOF) for
improved surface tension implementation is proposed and tested by comparison against a …

The numerical simulation of bubbly flows is challenging due to the unstable multiphase
interfaces with large density ratios and viscous ratios. The multiphase Smoothed Particle …

In this paper a three-dimensional (3D) volume of fluid (VOF) method is presented featuring
(i) an interface reconstruction technique based on piecewise linear interface …

A coupled volume-of-fluid and level set (VOSET) method, which combines the advantages
and overcomes the disadvantages of VOF and LS methods, is presented for computing …
