Published in 2019 at "Chemical Engineering Science"

DOI: 10.1016/j.ces.2019.02.013

Abstract: Abstract The bubble size distribution plays an important role in interfacial mass, momentum and energy transfer between bubbles and their carrier liquid in bubbly flow. Accurate modeling of the size distribution is therefore key. A… read more here.

Published in 2019 at "Journal of Fluid Mechanics"

DOI: 10.1017/jfm.2019.851

Abstract: Data from direct numerical simulations (DNS) of disperse bubbly flow in an upward vertical channel are used to develop a new second-moment closure for bubble-induced turbulence (BIT) in the Euler–Euler framework. The closure is an… read more here.
