🌋 Geothermal Flash Steam Plant: Separator Pressure and Optimum Net Power (2D)

Flow diagram of a single-flash geothermal plant: hot brine rises from the reservoir, flashes to steam in a separator, drives a turbine and leaves the rest as brine for reinjection. Set the well flow, the reservoir temperature, the separator pressure, the condenser pressure, the turbine efficiency and the parasitic load, and see the steam fraction, the specific work and the net power, together with the separator pressure that gives the most power. The isenthalpic flash balance, the optimum search, the Clausius-Clapeyron slope and the limits of the power curve are checked numerically, with four in-page numerical checks.
