Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This package contains very simple-to-use components to model coolant flows as needed to simulate cooling e.g., of electric machines:

Components: components like different types of pipe models
Examples: some test examples
Interfaces: definition of connectors and partial models (containing the core thermodynamic equations)
Media: definition of media properties
Sensors: various sensors for pressure, temperature, volume and enthalpy flow
Sources: various flow sources

Variables used in connectors:

EnthalpyFlowRate means the Enthalpy = cp_constant * m * T that is carried by the medium's flow.

Limitations and assumptions:

Splitting and mixing of coolant flows (media with the same cp) is possible.
Reversing the direction of flow is possible.
The medium is considered to be incompressible.
No mixtures of media is taken into consideration.
The medium may not change its phase.
Medium properties are kept constant.
Pressure changes are only due to pressure drop and geodetic height difference rho*g*h (if h > 0).
A user-defined part (0..1) of the friction losses (V_flow*dp) are fed to the medium.
Note: Connected flowPorts have the same temperature (mixing temperature)!
Since mixing may occur, the outlet temperature may be different from the connector's temperature.
Outlet temperature is defined by variable T of the corresponding component.
