Clearing of a polydisperse water aerosol by a laser pulse in the diffusive—convective regime

Abstract

Optically detected magnetic resonance spectra of pure and doped crystals of AgBr have been obtained at liquid helium temperatures. The free-electron g-value was found to be 1.49. This resonance is eliminated by electron-trapping dopants and enhanced by Cd2+ and P b 2 + . A resonance at g = 2.08 has been assigned as the free-hole resonance. This resonance is enhanced by electron-trapping dopants and by Cd2+ and P b Z + . Two strong resonances were found at g-values of 1.81 and 1.76. These resonances are thought to be from carriers trapped at intrinsic sites.

Numerical Modeling of Laser Heating and Evaporation of a Single Droplet

“…Consider a laser pulse propagating in air with some distribution of liquid droplets (Figure 15). Liquid droplets exceeding the boiling temperature evaporate significantly faster [15] than droplets in diffusive mode of evaporation. Thus, we can identify three different regions along the laser path.…”

“…Possible control of the heating and evaporation processes using laser energy deposition is also attractive for modern aerospace applications, e.g., efficient mixing, ignition, and combustion of liquid fuel droplets, laser wave propagation/attenuation in remote sensing, bleaching, control of size distribution of droplets, etc. [12][13][14][15]. Thus, understanding effects connected with the laser irradiation of liquid droplets is highly desirable.…”
