    • ISENTROPIC EFFICIENCY OF CENTRIFUGAL COMPRESSOR WORKING WITH REAL GAS 

      Autor: Oldřich, Jiří
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      The contribution deals with calculation of isentropic efficiency and also with calculation of isentropic process of real gas or gaseous mixtures. The method is based on numerical solution of basic definitional equation of ...

    • MARKET AND DEVELOPMENT TRENDS IN COGENERATION AND COMBINED HEAT AND POWER PLANTS 

      Autor: Slad, Jan; Pickard, Andreas; Strobelt, Frank
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      The transition of energy mix in Europe is placing greater focus on energy efficiency. Lawmakers in some of EU countries have already recognized that combined heat and power generation (cogeneration, CHP) can help increase ...

    • REGARDING CERTAIN AERODYNAMIC SOURCES OF NON-STATIONARY FORCE LOADS ON TURBINE PROFILES 

      Autor: Radnic, Tomáš; Luxa, Martin; Šimurda, David
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      The paper deals with selected phenomena present in a blade cascade flow field. The presented research was performed on prismatic blade cascades composed mostly of the tip and root sections of the last stage rotor blade of ...

    • THE EFFECT OF NOTCHES ON THE FATIGUE LIFE OF A NICKEL-BASE GAS TURBINE DISK MATERIAL 

      Autor: Eriksson, Robert; Moverare, Johan; Chen, Zhe; Simonsson, Kjell
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      Gas turbine disks carry significant load under high temperatures and may be subject to fatigue failure. Disks contain several notches in the form of the fir tree blade attachments. Low cycle fatigue tests were performed ...

    • THERMO-MECHANICAL FATIGUE ANALYSIS OF A STEAM TURBINE SHAFT 

      Autor: Nesládek, Martin; Jurenka, Josef; Bartošák, Michal; Růžička, Milan; Lutovinov, Maxim; Papuga, Jan; Procházka, Radek; Džugan, Jan; Měšťánek, Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      Increasing demands on the flexibility of steam turbines due to the use of renewable energy sources substantially alters the fatigue strength requirements of components of these devices. Rapid start-ups as well as the ...
