Local velocity scaling in upward flow to tooth impeller in a fully turbulent region
(EDP Sciences, 2019)The hydrodynamics and flow field were measured in an agitated vessel using 2-D Time Resolved Particle Image Velocimetry (2-D TR PIV). The experiments were carried out in a fully baffled cylindrical flat bottom vessel 400 ... -
Dispersion kinetics in mechanically agitated vessel
(EDP Sciences, 2019)Agitation of two immiscible liquids or solid-liquid suspension is a frequent operation in chemical and metallurgical industries. Prediction of mean drop/particle size and drop/particle size distribution (DSD) is vital for ... -
Measurement of drop size distribution time rate for liquid-liquid dispersion using IPI method
(EDP Sciences, 2019)The liquid-liquid dispersion properties are studied mainly by image analysis (IA) and Interferometric Particle Imaging (IPI). Drop sizes will be investigated in dilute dispersion since in this case the break up phenomena ... -
Image analysis of particle size: effect of light source type
(EDP Sciences, 2019)Agitation of two immiscible liquids or solid-liquid suspension is a frequent operation in chemical and metallurgical industries. The sizes of particles, bubbles or droplets can be determined by the Image Analysis Technique. ... -
A 3-Phase Current Transducer based on microfluxgate sensors
(Elsevier, 2019)Novel 3-phase DC/AC current transducer for 3-phase current lines is based on 8 integrated fluxgate sensors. Using full information from each sensor rather than gradiometric pairs, we suppress crosstalk between individual ... -
