Abstract: Measurement and simulation techniques have been developed for a two-phase flow to quantify and qualify a steam network and to determine the flow regime in the network. The development of these techniques makes it possible to create an intelligent monitoring system, which ensures that:

  • By the execution of the computational model the different states of the network can be simulated;
  • By using the principal of the local dynamic pressure measurement the distribution of the velocity in the cross-section of the pipes near the measurement points can be determined;
  • The mass transfer in the condense vessels can be determined in the backbone pipes;
  • By using mobile communication the measured data can be transferred immediately to the monitoring system; and
  • Algorithms and formulas can be created to determine the quality of the two-phase flow.

Keywords: Two-phase flow, identification, modelling, mass transfer network
