Lumped open tank model with an imposed constant pressure
The model OpenTank describes the storage of fluid in
liquid phase in an open tank.
Pressure and enthalpy are selected as state
variables.
The assumptions for this model are:
- The model is based on dynamic mass and energy balance
- Constant external pressure
- The static pressure head due to the liquid level is taken into
account
- Thermal energy transfer through the lateral surface is ensured
by the TankWall connector. The actual heat flow is
computed by the thermal energy model.
- Minimum liquid level with respect to tank height= 0
- Maximum liquid level with respect to tank height= 1
The model comprises two flow connectors and one lumped thermal
port connector. During normal operation the fluid enters the model
from the InFlow connector and exits from the
OutFlow connector. In case of flow reversal the fluid
direction is inversed
Modelling options
In the General tab the following options are
available:
- Medium: the user has the possibility to easily switch
Medium.
- HeatTransfer: selection between the different heat transfer
models available in ThermoCycle
