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 ... -
Interaction Experiment At The Bukov URF
(Česká tunelářská asociace ITA-AITES, 2019)The Interaction Experiment is being prepared by the CTU, ÚJV and ČGS for SÚRAO at the Bukov URF.The experiment is concerned with the study of mutual interactions between the candidate materials for the engineered barriers ... -
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 ... -
(Heisenberg-)Weyl Algebras, Segal-Bargmann Transform and Representations of Poincaré Groups
(IOP Publishing Ltd., 2018)In a recent paper (Havlíček M, Kotrbatý J, Moylan P and Pošta S 2018 J. Math. Phys. 59 2 021702 1-23) we described a novel treatment of the unitary irreducible representations of the Poincaré groups in 2, 3 and 4 space-time ... -
eXtended variational quasicontinuum methodology for lattice networks with damage and crack propagation
(Elsevier, 2017)Lattice networks with dissipative interactions are often employed to analyse materials with discrete micro- or meso-structures, or for a description of heterogeneous materials which can be modelled discretely. They are, ... -
Microstructure-Based Modeling of Elastic Functionally Graded Materials: One Dimensional Case
(Mathematical Sciences Publishers, 2008)Functionally graded materials (FGMs) are two-phase composites with continuously changing microstructure adapted to performance requirements. Traditionally, the overall behavior of FGMs has been determined using local ... -
Estimates of tillage and rainfall effects on unsaturated hydraulic conductivity in a small central European agricultural catchment
(MDPI AG, 2019)In arable land, topsoil is exposed to structural changes during each growing season due to agricultural management, climate, the kinetic energy of rainfall, crop and root growth. The shape, size, and spatial distributions ... -
Turbocharging of high performance compressed natural gas SI engine for light duty vehicle
(MECCA ČVUT, 2018)Natural gas as an automotive fuel has many benefits in comparison with traditional fossil fuels. Favorable anti-knock properties of methane allow us to utilize higher boost levels and the engine power than that of gasoline ... -
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 ... -
AMR Gradiometer for Mine Detection
(Elsevier Science, 2012)Anisotropic magnetoresistors (AMRs) are used to build an advanced mine detector. The sensing head involves a gradiometric pair of AMR sensors and a continuous-wave driven excitation coil, so the gradiometer is capable of ... -
Optimized Driving Cycle Oriented Control for a Highly Turbocharged Gas Engine
