Dynamics of bubble growth and detachment from a needle
Hasan N. Oguz,Andrea Prosperetti +1 more
TL;DR: In this article, the authors considered the growth and departure of bubbles from a submerged needle and showed the existence of two different growth regimes according to whether the gas flow rate into the bubble is smaller or greater than a critical value.

Sizes of bubbles produced by dissolved gas coming out of solution on the walls of pipes in flowing systems
TL;DR: In this article, the surface tension forces on gas bubbles adhering to the walls of pipes in flowing systems were derived for predicting the bubble radius on detachment, and gave good agreement with some experimenetal results for finite contact angles.

Bubble growth in flowing liquids
R.A.M. Al-Hayes,R.H.S. Winterton +1 more
TL;DR: In this article, experimental results have been obtained for mass transfer to air bubbles adhering to the inside wall of a tube with supersaturated liquid flowing past, and reasonable agreement with an analysis based on penetration theory was found.

Effect of gas bubbles on liquid metal heat transfer
TL;DR: In this paper, a theory was developed for heat transfer to liquid metals when the heat transfer surface is covered with gas bubbles, and the system analysed is that of constant heat flux to slug flow in a circular pipe.

Liquid metal superheat in forced convection
TL;DR: In this paper, the authors examined the effect of gas bubbles on superheat measurements and found that the number of bubbles will increase rapidly if the velocity in the cold pipework where the bubbles are precipitated, is raised.

Heat transfer effect of entrained gas in liquid sodium systems
TL;DR: In this article, a correlation was developed to determine the reduction in heat transfer caused by entrained inert gas in sodium-cooled liquid metal systems, and it was concluded that a reduction of heat transfer in a system having a low oxygen concentration (<5 ppm) occurs only if the heat transfer surface is unwetted or only partially wetted and entrained gas is present.
