This model describes a water-gas accumulator (the gas is modeled as ideal bi-atomic).

Water flows in and out through the interfaces at the component bottom (flow reversal supported).

The gas is supposed to flow in at constant temperature (parameter Tgin) and with variable flow-rate (GasInfl signal port), and to flow out by a valve operating in choked condition; the valve coefficient is determined by the working point at full opening (wg_out0,Tg0, Pg0) while the valve opening (in the range 0-1) is an input signal (OutletValveOpening signal port).
