Determination of Droplet Size, Velocity and Concentrations in Liquid/Liquid-Systems by a Combined Phase-Doppler and Rainbow Measurement Technique

摘要

The determination of process parameters within liquid/liquid two-phase flows including droplet size, velocity and mass transfer rates between the inner and outer phase is of basic interest for a consolidated understanding and an improved modelization of Liquid/Liquid-Extraction. Against this background a combination of the laseroptical measurement techniques Phase-Doppler-Anemometry and Rainbow-Refractometry will be discussed. Theoretical studies and experimental results will underline the improved possibilities of flow measurement offered by these advanced measurement devices.
