The computational fluid dynamics (CFD) method has been widely adopted and accepted in
the nuclear reactor safety analysis in the recent years. Especially, the application of …

Gas bubbles are of major importance in most metallurgical processes. They promote
chemical reactions, homogenize the melt, or float inclusions. Thus, their dynamics are of …

Bubble dynamics near a rigid boundary are associated with wide and important applications
in cavitation erosion in many industrial systems and medical ultrasonics. This classical …

For the simulation of bubbly flows, knowledge of the lift force as an interaction between gas
bubbles and a surrounding shear field is of great importance. The sign of the lift coefficient …

An extensive experimental database comprising air–water as well as steam-water upwards
vertical pipe flows for a pressure up to 6.5 MPa was used to investigate the effect of the …

A single bubble is placed in a solid-body rotating flow of silicon oil. From the measurement
of its equilibrium position, lift and drag forces are determined. Five different silicon oils have …

Lift and drag coefficients of deformable bubbles in intense turbulence determined from bubble
rise velocity Page 1 J. Fluid Mech. (2020), vol. 894, A20. c The Author(s), 2020. Published by …

The three-dimensional flow around two spherical bubbles moving in a viscous fluid is
studied numerically by solving the full Navier–Stokes equations. The study considers the …

Bubbles appear when a carbonated drink is poured in a glass. Very stable bubble chains
are clearly observed in champagne, showing an almost straight line from microscopic …

The buoyancy-driven motion of two identical gas bubbles released in line in a liquid at rest is
examined with the help of highly resolved simulations, focusing on moderately inertial …
