A Droplet Within the Spherical Model

Rough droplet model for spherical metal clusters

We study the thermally activated oscillations, or capillary waves, of a neutral metal cluster within the liquid drop model. These deformations correspond to a surface roughness which we characterize by a single parameter ∆. We derive a simple analytic expression determining ∆ as a function of temperature and cluster size. We then estimate the induced effects on shell structure by means of a per...

A Computer Modeling of Mie-Scattering by Spherical Droplets Within the Atmosphere

The Earth’s atmosphere is an environment replete with particles of differ-ent sizes with various refractive indices which affect the light radiation traveling through it. The Mie scattering theory is one of the well-known light scattering techniques ap-plicable to modeling of electromagnetic scattering from tiny atmospheric particles or aerosols floating in the air or within the clouds. In this...

Generation of thermocavitation bubbles within a droplet

High-speed video imaging was used to study the dynamic behavior of cavitation bubbles induced by a continuous wave (CW) laser into highly absorbing water droplets containing copper nitrate (CuNO4). The droplet lays horizontally on a glass surface and the laser beam (λ=975 nm) propagates vertically from underneath, across the glass and into the droplet. This beam is focused z=400 μm above the gl...
