COMPARISON BETWEEN 2D TURBULENCE MODEL ESEL AND EXPERIMENTAL DATA FROM AUG AND COMPASS TOKAMAKS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
In this article we have used the 2D fluid turbulence numerical model, ESEL, to simulate turbulent transport in edge tokamak plasma. Basic plasma parameters from the ASDEX Upgrade and COMPASS tokamaks are used as input for ...
PROTON STOPPING POWER OF DIFFERENT DENSITY PROFILE PLASMAS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
In this work, the stopping power of a partially ionized plasma is analyzed by means of free electron stopping and bound electron stopping. For the first instance, the RPA dielectric function is used, and for the latter ...
IMMOBILISATION OF HUMIC SUBSTANCES USING PLASMA MODIFICATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
This paper presents a study of the immobilization of humic substances (HSs) on a polypropylene (PP) nonwoven fabric. In order to attach the HSs, the PP nonwoven fabric was modified in a volume of nonthermal atmospheric ...
ENERGY EFFICIENCY OF PLANAR DISCHARGE FOR INDUSTRIAL APPLICATIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
Diffuse Coplanar Surface Barrier Discharge has proven its capabilities as an industry-ready plasma source for fast, in-line and efficient plasma treatment at atmospheric pressure. One parameter required by industry is ...
COMPARISON OF COOLING SCHEMES FOR HIGH HEAT FLUX COMPONENTS COOLING IN FUSION REACTORS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
Some components of the fusion reactor receives high heat fluxes either during the startup and shutdown or during the operation of the machine. This paper analyzes different ways of enhancing heat transfer using helium and ...
Replacing Natural Gas by Biogas — Determining the Bacterial Contamination of Biogas by PCR
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
A promising way of using biogas is to upgrade it to natural gas, which is referred to as Substitute Natural Gas (SNG) or biomethane. Biomethane, or biogas, is produced by biological processes of harnessing the ability of ...
A Pulverized Coal-Fired Boiler Optimized for Oxyfuel Combustion Technology
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This paper presents the results of a study on modifying a pulverized coal-fired steam boiler in a 250 MWe power plant for oxygen combustion conditions. The entry point of the study is a boiler that was designed for standard ...
Lifetime Assessment of a Steam Pipeline
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
The aim of this paper is to design a method for assessing the life of steam pipes for Czech power plants. The most widely-used material in Czech power plants is steel 15 128. Our findings may also be applied for international ...
Application of Induction Heating for Brazing Parts of Solar Collectors
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This paper reports on the application of induction heating for brazing parts of solar collectors made of Al alloys. The tube-flange joint is a part of the collecting pipe of a solar collector. The main task was to design ...
Energy Accumulation by Hydrogen Technologies
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Photovoltaic power plants as a renewable energy source have been receiving rapidly growing attention in the Czech Republic and in the other EU countries. This rapid development of photovoltaic sources is having a negative ...
