NUMERICAL MODELLING OF THE SOIL BEHAVIOUR BY USING NEWLY DEVELOPED ADVANCED MATERIAL MODEL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
This paper describes a theoretical background, implementation and validation of the newly developed Jardine plastic hardening-softening model (JPHS model), which can be used for numerical modelling of the soils behaviour. ...
HEAT TRANSFER ENHANCEMENT AND PRESSURE DROP OF GROOVED ANNULUS OF DOUBLE PIPE HEAT EXCHANGER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
This investigation was performed to experimentally investigate the enhancement of heat transfer and the friction of an annulus in a double pipe heat exchanger system with rectangular grooves in the turbulent flow regime. ...
TEARING MODES GROWTH RATE AMPLIFICATION DUE TO FINITE CURRENT RELAXATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
In this work, we explore the influence of perturbative wavelengths, shorter than those usually considered, on the growth rate γ of the tearing modes. Thus, we adopt an extended form of Ohm’s law, which includes a finite ...
USE OF DISC SPRINGS IN A PELLET FUEL MACHINE FOR PRESSURE REGULATION AND PREVENTION OF DAMAGE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
The use of biomass fuel pellets is becoming widespread as a renewable and environment-friendly energy. Pellet fuels are produced in various pellet machine types. Pellet machines encounter problems such as pressure ...
SILOXANES REMOVAL FROM BIOGAS USING ACTIVATED CARBON
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
SiO2 deposits which cause technical problems on combustion equipment are built by combustion of biogas containing siloxanes. Therefore, in these cases, the siloxanes must be removed from the biogas. For siloxane removal ...
FUNCTIONAL REALIZATIONS OF LIE ALGEBRAS AS NOETHER POINT SYMMETRIES OF SYSTEMS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
Functional realizations of Lie algebras are applied to the problem of determining Lie and Noether point symmetries of Lagrangian systems in N dimensions, particularly in the plane. This encompasses both the case of ...
ALGEBRAIC DESCRIPTION OF SHAPE INVARIANCE REVISITED
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
We revisit the algebraic description of shape invariance method in one-dimensional quantum mechanics. In this note we focus on four particular examples: the Kepler problem in flat space, the Kepler problem in spherical ...
DESIGN AND CONSTRUCTION OF A PROTOTYPE SOLAR UPDRAFT CHIMNEY IN ASWAN/EGYPT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
This work is part of a joint project funded by the Science and Technology Development Fund (STDF) of the Arab republic of Egypt and the Federal Ministry of Education and Research (BMBF) of the Federal Republic of Germany. ...
CALCULATIONS OF ION TRAJECTORIES AT MAGNETOPLASMA SEPARATION AND EXPERIMENTS WITH POLYATOMIC GASES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
Calculated trajectories of ions with different masses, indicating the possibility of a mixture separation, are obtained. Comparative experiments for plasma of monatomic and polyatomic gases (Ar, N2, CO2), upon combination ...
ELECTRICAL AND THERMODYNAMIC PROPERTIES OF A COLLAGEN SOLUTION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
This paper focuses on measurements of the electrical properties, the specific heat capacity and the thermal conductivity of a collagen solution (7.19% mass fraction of native bovine collagen in water). The results of our ...
