Single-phase vortices are a classic example of objects characterized by symmetry in the
distribution of all main parameters. The presence of inertial particles (or droplets) in such …

We investigate the effect of particle inertia on the merger of co-rotating dusty vortex pairs at
semi-dilute concentrations. In a particle-free flow, the merger is triggered once the ratio of …

A systematic numerical analysis is carried out on the multiplicity of patterns produced by
inertial particles dispersed in a fluid and localized gravitational convection developing in the …

Different phenomena related to the spontaneous accumulation of solid particles dispersed in
a fluid medium in microgravity conditions are discussed, with an emphasis on recent …

A completely new phenomenon of particle accumulation in vibrated non-isothermal
monodisperse suspensions of solid spheres (in a liquid) is analyzed. For the first time …

We study the role of phase change and thermal noise in particle transport in turbulent flows.
We employ a toy model to extract the main physics: Condensing droplets are modelled as …

We investigate the dynamics of heavy inertial particles in a flow field due to an isolated, non-
axisymmetric vortex. For our study, we consider a canonical elliptical vortex-the Kirchhoff …

How droplets grow rapidly from 10 to 50 μ m is an outstanding question in cloud physics. We
show theoretically and numerically that caustics, locations of multivalued droplet velocity, of …

We study the orientation dynamics of two-dimensional concavo-convex solid bodies that are
denser than the fluid through which they fall under gravity. We show that the orientation …

We study the motion of tiny heavy inertial particles advected by a two-dimensional inviscid
fluid flow, composed of N identical point vortices regularly placed on a ring and rotating as a …
