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 o…
Flow past a fixed spherical droplet: breaking of axisymmetry by an internal flow bifurcation
Pengyu Shi, Éric 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, Éric 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…
On the relevance of lift force modelling in turbulent wall flows with small inertial particles
Wei Gao, Pengyu Shi, Matteo Parsani +1
In particle-laden turbulent wall flows, lift forces can influence the near-wall turbulence. This has been recently observed in particle-resolved simulations, which, however, are to…
