Information

The model is designed to test the component Flow1D2ph when used as a condenser.
This model represent the fluid side of a condenser with an applied external heat flow. The operating fluid is water.
During the simulation, the inlet specific enthalpy and heat flux are changed, while maintaining the inlet flowrate constant:

• t=0 s. The initial state of the water is superheated vapour.
• t=10 s. Ramp increase of the heat flow extracted from the component. The steam condenses, causing a reduction of pressure and a flow rate transient decrease. At the end of the transient the outlet fluid is in subcooled liquid state.
• t=300 s. Step increase of the inlet enthalpy
• t=400 s. The heat flow is brought back to zero. The fluids evaporates, causing an increase of pressure and a surge of flow rate at the outlet..

Simulation Interval = [0...600] sec
Integration Algorithm = DASSL
Algorithm Tolerance = 1e-9
