SHAPE OF A NUCLEUS GROWING ON STRONGLY CURVED SURFACE OF A NANOFIBER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
The equilibrium shape of a critical nucleus has strong impact on important parameters of nucleation theory, such as nucleation rate. While on the flat substrate the growing nucleus has a shape of a spherical cap, a shape ...
AUTOMORPHISMS OF ALGEBRAS AND ORTHOGONAL POLYNOMIALS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
Suitable automorphisms together with complete classification of representations of some algebras can be used to generate some sets of orthogonal polynomials “at no cost”. This is also the case of nonstandard Klimyk-Gavrilik ...
EFFECTIVE USE OF ROTARY FURNACE SHELL HEAT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
Significant proportion of the total energy expenditure for the heat treatment of raw materials are heat losses through the shell of rotary furnace. Currently, the waste heat is not used in any way and escapes into the ...
ANALYSIS OF MECHANICAL PROPERTIES OF HYDROTHERMALLY CURED HIGH STRENGTH CEMENT MATRIX FOR TEXTILE REINFORCED CONCRETE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
The main objective of this article is to describe the influence of hydrothermal curing conditions in an autoclave device (different pressure and temperature), which took place at various ages of a fresh mixture (cement ...
TREATMENT OF NATURAL GAS BY ADSORPTION OF CO2
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
Apart from burning, one of the possible uses of natural gas is as a fuel for motor vehicles. There are two types of fuel from natural gas — CNG (Compressed Natural Gas) or LNG (Liquefied Natural Gas). Liquefaction of natural ...
UNSTEADY FLOW OF THIXOTROPIC COLLAGEN SUBSTANCE IN PIPES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
Unsteady flow of thixotropic liquid in pipes is solved by 1D and 2D numerical methods using the same constitutive equation — the only difference is in the radial diffusion of the structural parameter. Comparison shows that ...
A COMPACTING PROCESS OF THE EN AW 6060 ALLOY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
This study reports on an investigation of factors affect the process of compacting Al chips which are used to direct scrap processing through the forward extrusion method. EN AW 6060 chips of different geometry and types ...
EFFECTS OF INITIAL MOISTURE CONTENT ON THE PRODUCTION AND QUALITY PROPERTIES OF SOLID BIOFUEL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
The moisture content of densified biomass is a limit parameter influencing the quality of the solid biofuel. It influences its calorific value, density, mechanical strength and dimensional stability as well as the production ...
CONDENSATION OF WATER VAPOR IN A VERTICAL TUBE CONDENSER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
This paper presents an analysis of heat transfer in the process of condensation of water vapor in a vertical shell-and-tube condenser. We analyze the use of the Nusselt model for calculating the condensation heat transfer ...
PYROLYSIS OF BROWN COAL USING A CATALYST BASED ON W–Ni
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
Tars from pyrolysis of brown coal can be refined to obtain compounds suitable for fuel production. However, it is problematic to refine the liquids from brown coal pyrolysis, because high molecular compounds are produced, ...
