Terminal Velocity of a Bubble Rise in a Liquid Column
As it is known, buoyancy and drag forces rule bubble’s rise velocity in a liquid column. These forces are strongly dependent on fluid properties, gravity as well as equivalent’s diameter. This study reports a set of bubble rising velocity experiments in a liquid column using water or glycerol. Several records of terminal velocity were obtained. The results show that bubble’s rise terminal veloc...
متن کاملRise velocity of a swarm of large gas bubbles in liquids
This paper develops a procedure for estimation of the rise velocity of a swarm of large gas bubbles in a bubble column operating in the churn-turbulent flow regime. The large bubble swarm velocity is estimated by introducing two correction factors into the classical Davies—Taylor (1950) relation for rise of a single spherical cap bubble in a liquid » b "0.71Jgd b (SF) (AF) . The scale correctio...
متن کاملPreferential concentration and rise velocity reduction of bubbles immersed in a homogeneous and isotropic turbulent flow
The behavior of small spherical bubbles immersed in a homogeneous isotropic turbulent carrier flow of a heavier fluid has been experimentally studied. Air bubbles with diameters between 10 and 900 lm were injected in the test section of a horizontal water channel and allowed to interact with the turbulence induced by a grid located at the entrance to the test section. Point measurements of the ...

15 صفحه اولGrowth of bubbles in liquid
BACKGROUND Evolution of a gas injected in a liquid is analyzed using the example of the behavior of oxygen molecules in water in which bubbles of gas molecules grow slowly by attachment of gas molecules to bubbles, the bubbles then associate and finally flow up to the liquid-gas interface and pass into the gas phase. RESULTS Two methods are considered for gas injection in a liquid, insertion ...
