Abstract

We report on the experimental studies of the influence of two different types of hydrodynamic perturbations on the characteristics of laser radiation scattering in the near-water aerosol layer. Laboratory experiment was carried out in a tank with flowing and standing aerated water. The first type of hydrodynamic perturbations was created by a streamlined obstacle at the tank bottom; the second one - by rotating propellers. Two sorts of statistical amplitude distribution of red laser light scattering in a near-water aerosol located above the perturbation region are established. It is established that various statistical distributions of the amplitudes of the laser radiation scattering pulses on the particles of the near-water aerosol and, accordingly, the different aerosol distributions in size, correspond to these various hydrodynamic perturbations. Normalized amplitude distribution histograms of light scattering are compared.
