      Autor: Peciar , Peter; Macho , Oliver; Eckert , Maroš; Kabát , Juraj; Gabrišová , Ľudmila; Kotora , Peter; Fekete , Roman; Peciar , Marián
      (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 ...
    • HEAT TRANSFER ENHANCEMENT AND PRESSURE DROP OF GROOVED ANNULUS OF DOUBLE PIPE HEAT EXCHANGER 

      Autor: Sunu Wijaya, Putu; Rasta Made, I
      (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. ...
    • SURFACE CONSOLIDATION OF WALL PAINTINGS USING LIME NANOSUSPENSIONS 

      Autor: Vojtěchovský , Jan
      (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 ...
    • USE OF DISC SPRINGS IN A PELLET FUEL MACHINE FOR PRESSURE REGULATION AND PREVENTION OF DAMAGE 

      Autor: Çelik , İsmet; Güneş Can, Ebubekir
      (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 

      Autor: Vagenknechtová , Alice; Ciahotný , Karel; Vrbová , Veronika
      (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 ...
    • IMPLEMENTATION OF 3D VOF TRACKING ALGORITHM BASED ON BINARY SPACEPARTITIONING 

      Autor: Kolařík , Filip; Patzák , Bořek
      (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 ...
    • EXPERIMENTAL DETERMINATION OF TEMPERATURES IN SPARK GENERATED BUBBLES OSCILLATING IN WATER 

      Autor: Vokurka , Karel
      (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 ...
