Model of a barometric condenser including the barometric leg.
The incoming cooling water is sprayed in the condenser and mixes
with the incoming steam flow. It is assumed that the residence time
of the droplets in the condenser is equal to Tr. The
pressure p in the condenser corresponds to the droplet
temperature Tl plus the terminal temperature
difference Tt, which is assumed to be constant for
simplicity.
In most cases, barometric condensers discharge into tanks that
have a much larger diameter and a much larger mass storage than the
barometric leg. Therefore, the effects of the leg dynamics, i.e.
the changes of the level in the pipe and the delay between the
temperature at the condenser outlet and the temperature at the pipe
outlet, are negligible. By setting neglectLegDynamics =
true, the mass flow rate and specific enthalpy at the
barometric leg outlet are assumed to be the same as the ones at the
condenser outlet.
If neglectLegDynamics = false, the effects of mass,
momentum and energy storage in the barometric leg are also
accounted for. This is currently not yet implemented.
