Paper Abstract

A new approach to the determination of size distribution and velocity distribution functions of the polydisperse aerosol and hydrosol particles systems is considered. This approach is based on the laser Doppler anemometry (LDA) technique, and exploits the dependence of the translational particle velocity in a flow or in a still medium on the size and (possible) on other parameters of a particle. The most commonly used differential LDA measuring system is considered specially including the influence of its instrumental function on the shape of the measured spectra. It is shown that the intrinsic shape of the integral Doppler spectrum is determined by three functions characterizing the particles in the system: size distribution, translational velocity distribution, and the dependence of the light scattering cross-section of a particle on its size and the scattering angle.
