Streszczenie: This study deals with development and application of the optic methods for investigation of the two-phase flows with high concentration of dispersed phase (optically opaque). The original three-fiber optical probe of the laser Doppler anemometer (LDA), operating in the regime of back-scattering, was developed. The velocities and concentrations of particles in a circulating fluidized bed were measured. The modified two-fiber optic probe of the reflecting type was developed; this sensor was used for measurements of the liquid film thickness inside the distillation column. The field of its application includes high-concentrated two-phase flows, difficult-to-reach places (behind an obstacle), and full-scale objects. The method of refractive index matching (RIM) was developed for investigation of the highly concentrated solid-liquid flows. The turbulent regime of liquid filtering inside the flow passage of the regular packed bed was investigated with application of LDA and RIM technique.
