SIGNAL SIMULATION FOR LASER DOPPLER ANEMOMETER APPLIED TO PARTICLES SIZE AND VELOCITY MEASUREMENT IN TWO-PHASE FLOW
Annotation
A method is developed for calculation of laser Doppler anemometer signal caused by light scattered at a particle of the size of the order of or larger than the sounding light beam cross-section. The method employs the concept of virtual receiver in the frames of geometric optics for a spherical particle. Formulae for evaluation of virtual receiver parameters for various order of scattering are presented. Effectiveness of the proposed approach is demonstrates by comparison of simulated signal with experimentally obtained one.
