ArbitraryProcess(; name, inter_state, process, fluid)

Component: ArbitraryProcess

Once the two states in a node are determined, the remaining 3 states can be obtained from these two known states. In ArbitraryProcess, 2 states need to be determined.

Connectors:

• in: Inlet of process
• out: Outlet of process

• inter_state: One state to be determined. There are 7 options:
  • "P": Giving state pressure
  • "H": Giving state enthalpy
  • "T": Giving state temperature
  • "D": Giving state density
  • "S": Giving state entropy
  • "Q_0": Giving saturated liquid(0 is value of the state, automatically passed into ODESystem)
  • "Q_1": Giving saturated vapor(1 is value of the state, automatically passed into ODESystem)
• process: Another state to be determined. There are 5 options:
  • "P": Giving state pressure
  • "H": Giving state enthalpy
  • "T": Giving state temperature
  • "D": Giving state density

DThermalStates(; name, state, value, u0)

Component: DThermalStates

The DThermalStates make the value of state changes over time.

IsentropicProcess(; name, inter_state, fluid)

Component: IsentropicProcess

  • "S": Giving state entropy
  • "Q_0": Giving saturated liquid(0 is value of the state, automatically passed into ODESystem)
  • "Q_1": Giving saturated vapor(1 is value of the state, automatically passed into ODESystem)
• fluid: The fluid passing throught the component, default: "Water"

IsobaricProcess(; name, inter_state, fluid)

Component: IsobaricProcess

The Pressure is constant during the process.

Once the two states in a node are determined, the remaining 3 states can be obtained from these two known states. In IsobaricProcess, pressure are the same from inlet to outlet. So another state still needed.
