Effect of Particle Image Velocimetry Setting Parameters on Local Velocity Measurements in an Agitated Vessel
Autor: Šulc R.; Ditl P.; Jašíková D.; Kotek M.; Kopecký V.; Kysela B.
(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 ... -
Estimating the limits of renewable energy from phytomass
Autor: Ditl P.
(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 ... -
HEAT TRANSFER BETWEEN GAS AND NON-COALESCENT LIQUID IN A BUBBLE COLUMN
Autor: Žižka M.; Šulc R.; Ditl P.
(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 ... -
Local Energy Dissipation Rate in an Agitated Vessel-a Comparison of Evaluation Methods
Autor: Šulc R.; Ditl P.
(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 ... -
Local Turbulent Energy Dissipation Rate in an Agitated Vessel: Experimental and Turbulence Scaling
Autor: Ditl P.; Šulc R.; Pešava V.; Jasikova D.
(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 ... -

Autor: Šulc R.; Ditl P.; Fořt I.; Jašíková D.; Kotek M.; Kopecký V.; Kysela B.
(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 ... -
The Potential of Energy Savings in Oxygen Production by Pressure Swing Adsorption
Autor: Šulc R.; Ditl P.
(AIDIC Servizi S.r.l., 2021)The pressure swing adsorption (PSA) units are widely used as an oxygen source. The second PSA unit outgoing stream contains a dry mixture of O2 in N2 that is mostly exhausted into the atmosphere. Utilization of this stream's ... -
The Potential of Liquefied Oxygen Storage for Flexible Oxygen-Pressure Swing Adsorption Unit
Autor: Šulc R.; Ditl P.
(AIDIC Servizi S.r.l., 2021)The pressure swing adsorption (PSA) units are widely used as an oxygen source. Start-up time taking minutes is an undeniable advantage of PSA technology compared to cryogenic air separation start-up time taking hours or ... -
Progress in the evaluation of local energy dissipation rate in an agitated vessel
Autor: Šulc R.; Ditl P.
(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 ... -
