Simple components for 1-dimensional incompressible thermo-fluid flow models
Basic components (pipes, valves)
Examples that demonstrate the usage of the FluidHeatFlow components
Connectors and partial models
Ideal sensors to measure port properties
Ideal fluid sources, e.g., ambient, volume flow
- 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
- Pressure p
- flow MassFlowRate m_flow
- SpecificEnthalpy h
- flow EnthalpyFlowRate H_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 differnence 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.
- Additional components like tanks (if needed)
