文摘

The mass, momentum and energy solver calculates pressure, mixture enthalpy and mass fractions for the system volumes and mass flows for the flow branches. Thermodynamic state in the volumes is solved assuming local phase equilibrium. Rigorous seawater thermodynamic and transport properties calculation is included. Large brine recycling MSF plant model demonstrates the advanced and novel features. The model predicts the system state and dynamics in a qualitatively reasonable way; the simulation data is provided in Supplementary material.
