Information

This is a model of a distribution network for steam heating systems. The model utilizes a split-medium approach with two separate medium declarations between liquid (condensate return) and vapor (steam supply) states. The piping network features:

• a connection model with fixed hydraulic resistance and no heat loss in the condensate return pipe segments;
• a dummy pipe model with no hydraulic resistance and no heat loss for the steam supply pipes; and
• a dummy pipe model with no hydraulic resistance and no heat loss for the end of the distribution line (after the last connection).
