Rise regimes of freely rising droplets with a moderate viscosity ratio
Pengyu Shi, Dirk Lucas, Jie Zhang +2
The dynamics of buoyant droplets rising freely in a large body of an immiscible liquid is investigated numerically for a moderate drop-to-fluid viscosity ratio . We focus…

Flow past a fixed spherical droplet: breaking of axisymmetry by an internal flow bifurcation
Pengyu Shi, Ãric Climent, Dominique Legendre
Direct numerical simulations of a uniform flow past a fixed spherical droplet are performed to determine the parameter range within which the axisymmetric flow becomes unstable. Th…

Wake instability of a fixed spherical droplet with a high drop-to-fluid viscosity ratio
Pengyu Shi, Ãric Climent, Dominique Legendre
Direct numerical simulations of a uniform flow past a fixed spherical droplet are performed to investigate the parameter range within which the axisymmetric flow becomes unstable d…
