On buoyancy in disperse two-phase flow and its impact on well-posedness of two-fluid models
Rui Zhu, Yulan Chen, Katharina Tholen +2
The Maxey-Riley-Gatignol equation for the flow around a sphere at low particle Reynolds number tells us that the fluid-particle interaction force decomposes into a contribution fro…

Coarse-graining particulate two-phase flow
Thomas Pähtz, Yulan Chen, Rui Zhu +2
To acquire the ability to numerically study the rheology of particulate two-phase flows that lack scale separation, we present a general method to average or coarse-grain the equat…
