    • EFFECT OF TUBE PITCH ON HEAR TRANSFER IN SPRINKLED TUBE BUNDLE 

      Autor: Kracík , Petr; Pospíšil , Jiří
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Water flowing on a sprinkled tube bundle forms three basic modes: the Droplet mode (the liquid drips from one tube to another), the Jet mode (with an increasing flow rate, the droplets merge into a column) and the Membrane ...

    • EFFECTS OF INITIAL MOISTURE CONTENT ON THE PRODUCTION AND QUALITY PROPERTIES OF SOLID BIOFUEL 

      Autor: Matúš , Miloš; Križan , Peter; Beniak , Juraj; Šooš , Ľubomír
      (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 ...

    • ELECTRODYNAMIC LOUDSPEAKER-DRIVEN ACOUSTIC COMPRESSOR 

      Autor: Šoltés , Martin; Červenka , Milan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      An acoustic compressor is  built  using the acoustic resonator which shape was optimized for a maximum acoustic pressure amplitude and a low-cost compression driver.  Acoustic compressor is built  by installing  a suction ...

    • PYROLYSIS OF BROWN COAL USING A CATALYST BASED ON W–Ni 

      Autor: Jílková , Lenka; Ciahotný , Karel; Kusý , Jaroslav
      (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, ...

    • SIMULATION MODEL BASED ON REGIONAL DEVELOPMENT AND VIRTUAL CHANGES 

      Autor: Dlask , Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      This paper reports on change as an indicator that can be provide more focused goals in studies of development. The paper offers an answer to the question: How might management gain information from a simulation model and ...

    • UNSTEADY FLOW OF THIXOTROPIC COLLAGEN SUBSTANCE IN PIPES 

      Autor: Žitný , Rudolf; Landfeld , Aleš; Skočilas , Jan; Štancl , Jaromír; Flegl , Vlastimil; Houška , Milan
      (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 ...
