DOI: 10.2478/rtuect-2020-0059 This paper proposes a two-stage approach to choose the priority municipal units for implementing required energy efficiency measures in a district heating system. On the first stage the existing state of district heating system of Irkutsk region (Eastern Siberia) was analysed. On the second stage the choice of municipal units is considered as the Multiple Criteria Decision Analysis (MCDA) problem....

The heat release dissipation on the heater was performed by passing a controlled three-phase rectified electric current through a tube with a pulse duration of τimp = 60-300 ms with a heating rate of 1000-6000 K/s. We studied the formation dynamics and the structure of the vapor-liquid layer near the heat releasing wall and monitored the temperature state of the wall depending on the parameters of the heater's flow and the intensity ...

The non-stationary heat release is most difficult for modeling, because many of the existing researches are based on analytical expressions for the fluid temperature distribution. The basic stages of the explosive boiling are: (i) heating of the wall to the nucleation temperature; (ii) nucleation of the isolated bubbles; (iii) merging of bubbles and coverage of the entire surface by the steam phase; (iv) heating of the surface to the Leidenfrost temperature and transition to the ...
