Bubble Rise in a Liquid With a Surfactant Gas, in Particular Carbon Dioxide

Harper, J F (Victoria University of Wellington, 2007)

When a gas bubble rises in a surfactant solution, the velocity field and the distribution of surfactant affect each other. This paper gives the theory for small Reynolds and internal Peclet numbers if the surfactant is ...
Bubbles Rising in Line: Why is the First Approximation So Bad?

Harper, J F (Victoria University of Wellington, 1997)

An analytical theory is given for the viscous wake behind a spherical bubble rising steadily in a pure liquid at high Reynolds number, and for that wake's effect on the motion of a second bubble rising underneath the first. ...
Evaluating methane outputs from an area of submarine seeps along the northern Hikurangi Margin, New Zealand

Higgs, Benjamin (Victoria University of Wellington, 2016)

Collated global marine surveys have documented large volumes of gaseous methane able to escape from deeply-buried deposits into global oceans as seeps. Seeps are evident where permeable faults and fracture networks allow ...
