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 ...
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 ...
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 ...
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 ...
Estimating the limits of renewable energy from phytomass
(Elsevier B.V., 2022)
The energy production from phytomass on agricultural and forest lands can be calculated on the basis of the annual production of hydrocarbons (cellulose, starch, sugar, etc.), without needing to take into account the type ...
A Technical and Economic Evaluation of Two Different Oxygen Sources for a Small Oxy-Combustion Unit
(Elsevier, 2021)
Oxy-combustion is a feasible CO2 capture method in the power and heat generation sector. This paper aims to propose a methodology for assessing two oxygen production technologies for small-scale oxy-combustion units: i) ...
Effect of Particle Image Velocimetry Setting Parameters on Local Velocity Measurements in an Agitated Vessel
(VCH, 2019)
Although they are obtained under the same conditions, results on the flow field in an agitated vessel achieved using particle image velocimetry (PIV) may vary due to differences in the PIV conditions. The influence on ...
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 ...
