The Decoupled Algorithmula was validated by simulating a parallel flow heat exchanger, consisting of these segments. The procedure employed was non-iterative. We now have to adapt the method for other types of heat flow arrangements. A method of achieving this is by using the decoupled algorithm /6,9/.

As the boiling temperature and the wet steam volume are dependent on pressure, the mass and momentum balances are required to complement the energy balance.

Power Generating Unit Modelh Figure 11.1. This represents the highest simulation level. In addition to the steam generator, the PGU incorporates some further heat exchangers, such as the steam condenser, feed-water heaters, air heater, piping, etc., as subsystems. They can all be simulated in a similar manner to the steam gen
