♨️ Geothermal Single-Flash Plant: Separator Temperature and Turbine Power (2D)

Flow diagram of a single-flash geothermal power plant: hot brine from the wells flashes to steam in a separator, the steam drives a turbine and a condenser, and the remaining brine is reinjected. Set the reservoir, separator and condenser temperatures, the turbine efficiency and the brine flow, and see the steam fraction, the turbine work, the net power and the best separator temperature on a temperature-entropy diagram. Steam properties, the separator balance, the optimum and the second law are checked numerically, with four in-page numerical checks.
