ANALYSIS OF DALLARA T12 RACE CAR FRONT WING VIBRATIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
This work investigates aerodynamic elements’ vibrations of high-speed vehicles on the example of the Dallara T12 race car front wing. Made up energy spectrums of wing vibrations for three specific cases arising during ...
THE TIME DIFFERENCE IN EMISSION OF LIGHT AND PRESSURE PULSES FROM OSCILLATING BUBBLES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
Oscillations of spark-generated bubbles are studied experimentally. In this work, an attention is paid to the time difference in the radiation of light flashes and pressure pulses from a bubble at the final stages of the ...
CHARACTERIZATION OF RECYCLED LINEAR DENSITY POLYETHYLENE/IMPERATA CYLINDRICA PARTICULATE COMPOSITES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
Water-sachets made from low density polyethylene (LDPE) form a bulk of plastic wastes which creates environmental challenges, while certain species of plants like Imperata cylindrica constitute large portion of weeds on ...
APPLICATION OF THE TEMPERATURE OSCILLATION METHOD IN HEAT TRANSFER MEASUREMENTS AT THE WALL OF AN AGITATED VESSEL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The Temperature Oscillation Infra-Red Thermography (TOIRT) was used to measure convective heat transfer coefficients at the inner vertical wall of an agitated and baffled vessel. Two impellers were used: an axial six-blade ...
STABILITY OF SYNTHESIZED SILVER NANOPARTICLES IN CITRATE AND MIXED GELATIN/CITRATE SOLUTION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The study focuses on an investigation of the influence of both citrate and mixed gelatin/citrate as a reductant and stabilizer on the colloidal stability of silver nanoparticles (AgNPs)synthesized by a chemical reduction ...
OPTIMALIZATION OF PHOTOREACTOR GEOMETRY FOR THE CULTIVATION OF CHLAMYDOMONAS REINHARDTII
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
At the present time, a great attention is being paid to the use of algae. Algae can adapt to different conditions and can produce substances corresponding to responsible environments. The main problem in their cultivation ...
ŽAMPA’S SYSTEMS THEORY: A COMPREHENSIVE THEORY OF MEASUREMENT IN DYNAMIC SYSTEMS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The article outlines in memoriam Prof. Pavel Žampa’s concepts of system theory which enable us to devise a measurement in dynamic systems independently of the particular system behaviour. From the point of view of Žampa’s ...
PARTICLE MOTION ON THE SURFACE OF A CONCAVE SOIL-TILLING DISK
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
Relative particle motion on the internal rough surface of a concave soil-tilling disk, which rotates around horizontal axis under a soil reaction force, has been considered. A disk blade is positioned in a vertical plane, ...
ULTRA-HIGH-PERFORMANCE FIBRE-REINFORCED CONCRETE UNDER HIGH-VELOCITY PROJECTILE IMPACT - PART 2. APPLICABILITY OF PREDICTION MODELS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
Semi-infinite targets of Ultra-High-Performance Fibre-Reinforced Concrete with various fibre volume fractions were subjected to the high-velocity projectile impact using in-service bullets. In this study, a variety of ...
THE CHARACTERIZATION OF ANODIC OXIDE LAYERS ON SELECTED BIO-COMPATIBLE TITANIUM ALLOYS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
Oxide layers on titanium alloy surfaces have an influence on bio-compatibility and corrosion resistance. In order to improve them, properties of oxide layers are examined. The oxide layer can be prepared by different methods ...
