Information

Model Tank_pL represents a liquid receiver. It is assumed to be in thermodynamic equilibrium at all times, i.e. the vapor and liquid are saturated at the given pressure. It is modeled with a dynamic energy and mass balances.

The exhaust flow rate is defined as saturated liquid while the supply flow rate coming from the inlet can be either subcooled (in which case the receiver pressure is going to decrease), saturated (in which case the receiver pressure remains constant) or two-phase (in which case the receiver pressure is going to increase).

It uses L , the relative level, and p, pressure, as state variables

It only requires one saturation call to the thermodynamic properties.

Modelling options

In the Initialization tab the following options are availabe:

• impose_L: if true, the level of the tank is imposed during Initialization
• impose_pressure: if true, the pressure of the tank is imposed during Initialization
• SteadyState_p: if true, the derivative of the pressure of the tank is set to zero during Initialization
• SteadyState_L: if true, the derivative of the level of the tank is set to zero during Initialization
