Simulation of laser drilling of Inconel X-750 and Ti-5Al-2.5Sn sheets using COMSOL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
This study aims to investigate the simulation of laser drilling processes on Inconel X-750 and Ti-5Al-2.5Sn sheets. To this end, COMSOL Multiphysics 5.2 software was employed to carry out the virtual experiments. A JK 701 ...
CO2 power cycle chemistry in the CV Řež experimental loop
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
Power cycles using carbon dioxide in a supercritical state (sc-CO2) can be used in both the nuclear and non-nuclear power industry. These systems are characterized by their advantages over steam power cycles, e. g., the ...
Detailed modelling and analysis of digital mho distance relay with single-pole operation
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
This paper introduces a methodology for modelling a digital admittance-type distance relay using PSCAD/EMTDC. The proposed distance relay was tested in a simulation of the Brazilian power grid with predetermined fault ...
Corn starch doped with sodium iodate as solid polymer electrolytes for energy storage applications
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The concern about environmental problems has inspired a of energy storage devices from natural sources. In this study, solid polymer electrolyte (SPE) films made from corn starch doped with different compositions of sodium ...
On a static and dynamic calibration of thermochromic liquid crystals
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The paper deals with a static and dynamic calibration of selected wide-range thermochromic liquid crystals (TLC - SolarDust 24C), which are very easy to ingest and can provide accurate information on the temperature ...
NUMERICAL SIMULATION OF A SINGLE RING INFILTRATION EXPERIMENT WITH hp-ADAPTIVE SPACE-TIME DISCONTINUOUS GALERKIN METHOD
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
We present a novel hp-adaptive space-time discontinuous Galerkin (hp-STDG) method for the numerical solution of the nonstationary Richards equation equipped with Dirichlet, Neumann and seepage face boundary conditions. The ...
Performance characteristics of Hopkinson’s set-up pneumatic launcher
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The paper presents a performance characteristics of a pneumatic launcher, which is an important element of the split Hopkinson bar set-up (SHPB) at the Department of Military Engineering and Infrastructure (the Military ...
Stationary solutions of incompressible viscous flow in a wall-driven semi-circular cavity
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
Stationary numerical solutions of incompressible viscous flow inside a wall-driven semicircular cavity are presented. After a conformal mapping of the geometry, using a body-fitted mesh, the Navier-Stokes equations are ...
MOONLIGHT: A NEW LUNAR LASER RANGING RETROREFLECTOR AND THE LUNAR GEODETIC PRECESSION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Since the 1970s Lunar Laser Ranging (LLR) to the Apollo Cube Corner Retroreflector (CCR) arrays (developed by the University of Maryland, UMD) supplied almost all significant tests of General Relativity (Alley et al., 1970; ...
THE PAST AND THE FUTURE OF DIRECT SEARCH OF GW FROM PULSARS IN THE ERA OF GW ANTENNAS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
In this paper we will give an overview of the past and present status of Gravitational Wave (GW) research associated with pulsars, taking into account the target sensitivity achieved from interferometric laser GW antennas ...
