Local Energy Dissipation Rate in an Agitated Vessel-a Comparison of Evaluation Methods
(Springer, 2018)
There are two main groups of local turbulent energy dissipation rate (epsilon) evaluation methods, namely (i) velocity gradient methods and (ii) fitting the energy spectrum function. We calibrated our measurements and then ...
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 ...
HEAT TRANSFER BETWEEN GAS AND NON-COALESCENT LIQUID IN A BUBBLE COLUMN
(AIDIC Servizi S.r.l., 2019)
Multiphase contactors, e.g. bubble columns, are often used in operations accompanied by heat transfer between the phases. The effect of multi-orifice aerator for the heat transfer between gas and the non-coalescent liquid ...
Drop Size Evolution Kinetics in a Liquid-liquid Dispersions System in a Vessel Agitated by a Rushton Turbine
(AIDIC Servizi S.r.l., 2019)
Processes in which mixing plays a crucial role in increasing mass transfer, interfacial surface, and homogenization are frequently and widely used throughout the industry. Agitation of immiscible liquids or solid-liquid ...
РАЗДЕЛЕНИЕ ГАЗОВ МЕТОДИКОЙ PSA В ЭНЕРГЕТИКЕ
(Russian Chemistry Society, 2018)
В статье описывается технология разделения газов, называемая адсорбцией под действием давления. Модели, описывающие явления, вызванные коккой, основаны на основах структурного программирования и решаются с использованием ...
Local Turbulent Energy Dissipation Rate in an Agitated Vessel: Experimental and Turbulence Scaling
(Pleiades Publishing Ltd., 2018)
The hydrodynamics and the flow field in an agitated vessel were measured using 2-D time resolved particle image velocimetry (2-D TR PIV). The experiments were carried out in fully baffled cylindrical flat bottom vessels ...
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. ...
Time evolution of the drop size distribution for liquid–liquid dispersion in an agitated tank
(Springer, 2018)
Agitating two immiscible liquids or a solid–liquid suspension is an operation frequently performed in the chemical and metallurgical industries, for example, in suspension/emulsion polymerization, heterogeneous/phase-transfer ...
Progress in the evaluation of local energy dissipation rate in an agitated vessel
(Russian Chemistry Society, 2018)
The scale-up of processes such as liquid-liquid dispersion, gas-liquid dispersion, powder dispersion, flocculation, the scale of segregation at chemical reactions requires correct knowledge of local turbulent energy ...
