Corona splashing triggered by a loose monolayer of particles

نویسندگان

چکیده

In nature, high-speed raindrops often impact and spread on particulate surfaces (e.g., soil, plant leaves with spores or pollen). We study the dynamics of droplet a loosely packed monolayer particles by combining experimental mathematical approaches. find that presence mobile lowers critical velocity at which exhibits corona splashing, as particle area fraction is systematically increased. rationalize this observation considering jamming frictional spreading rim. Elucidating splashing transition drop bed can lead to better understanding soil loss erosion from falling raindrops.

Incipient Motion of Sediment Particles over Loose

New experimentals work were conducted to study the effects of sediment deposits’ thickness on the incipient motion of particles in a rigid rectangular channel. The results show that the deposits’ thickness significantly affects the channel’s ability to erode the sediment deposits. New equations were derived taking into account the effects of deposits’ thickness.

Adhesive loose packings of small dry particles.

We explore adhesive loose packings of small dry spherical particles of micrometer size using 3D discrete-element simulations with adhesive contact mechanics and statistical ensemble theory. A dimensionless adhesion parameter (Ad) successfully combines the effects of particle velocities, sizes and the work of adhesion, identifying a universal regime of adhesive packings for Ad > 1. The structura...

Thermodynamics of a binary monolayer of Ising dipolar particles.

Thermodynamic behavior of a binary monolayer of Ising dipolar particles is studied using numerical simulation. The thermal equilibrium states of the system under the canonical ensemble are observed. The boundary of gas-liquid phase is determined from the power law growth of critical clusters. But that temperature is slightly lower than that of solidification. So it means that this system does n...
