CYCLIC TEMPERATURE LOADING RESIDUAL FLEXURAL STRENGHT OF REFRACTORY SLABS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)This paper describes the effect of cyclic elevated temperature loading on refractory slabs made from high performance, fibre reinforced cement composite. Slabs were produced from aluminous cement-based composites, reinforced ... -
EXPERIMENTAL DETERMINATION OF TEMPERATURES IN SPARK GENERATED BUBBLES OSCILLATING IN WATER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)The surface temperatures of the plasma core in the final stages of the first contraction phase of spark-generated bubbles oscillating under ordinary laboratory conditions in a large expanse of water are determined ... -
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. ... -
IMPLEMENTATION OF 3D VOF TRACKING ALGORITHM BASED ON BINARY SPACE-PARTITIONING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)The paper focuses on modelling free surface flow. The interface is modelled using the Volume-Of-Fluid method, where the advection of volume fractions is treated by a purely geometrical method. The novelty of the work lies ... -
MODIFICATION OF POWDER MATERIAL BY COMPACTION PROCESSING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)There are different criteria for assessing the appropriateness of an agglomeration technology in the deployment processing of dry, fine and dirty dust burdening in the communal and working environment. Besides the benefit ... -
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 ... -
SURFACE CONSOLIDATION OF WALL PAINTINGS USING LIME NANO-SUSPENSIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)Within the field of the conservation of historical and cultural monuments, lime nanosuspensions are still a relatively new and unexplored material. This study examines their effect on the consolidation of architectural ... -
THE IMPACT OF SELECTED PROCESSES AND TECHNOLOGICAL PARAMETERS ON THE GEOMETRY OF THE WELD POOL WHEN WELDING IN SHIELS GAS ATMOSPHERE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)This paper is focused on welding with a consumable electrode in a gas shield atmosphere and its main aim is to show the influence of selected processes and technological parameters on the geometry of the weld pool in terms ... -
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 ...
