    • JET ENGINE INLET DISTORTION SCREEN AND DESCRIPTOR EVALUATION 

      Autor: Pečinka , Jiří; Bugajski Thomas, Gabriel; Kmoch , Petr; Jílek , Adolf
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      Total pressure distortion is one of the three basic flow distortions (total pressure, total temperature and swirl distortion) that might appear at the inlet of a gas turbine engine (GTE) during operation. Different numerical ...

    • NUMERICAL MODELLING OF THE SOIL BEHAVIOUR BY USING NEWLY DEVELOPED ADVANCED MATERIAL MODEL 

      Autor: Veselý , Jan
      (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. ...

    • PRELIMINARY STUDY ON COMBUSTION AND OVERALL PARAMETERS OF SYNGAS FUEL MIXTURES FOR SPARK IGNITION COMBUSTION ENGINE 

      Autor: Toman , Rastislav; Polóni , Marián; Chríbik , Andrej
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      This paper presents a numerical study on a group of alternative gaseous fuels – syngases, and their use in the spark-ignition internal combustion engine Lombardini LGW 702. These syngas fuel mixtures consist mainly of ...

    • PROPERTIES AND MICROSTRUCTURE OF CEMENT PASTE INCLUDING RECYCLED CONCRETE POWDER 

      Autor: Topič , Jaroslav; Prošek , Zdenek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      The disposal and further recycling of concrete is being investigated worldwide, because the issue of complete recycling has not yet been fully resolved. A fundamental difficulty faced by researchers is the reuse of the ...

    • TEARING MODES GROWTH RATE AMPLIFICATION DUE TO FINITE CURRENT RELAXATION 

      Autor: Mendonça da Silveira , Francisco Eugenio
      (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 ...
