This information is part of the Modelica Standard Library maintained by the Modelica Association.
1st test example: SimpleCooling
A prescribed heat source dissipates its heat through a thermal conductor to a coolant flow. The coolant flow is taken from an ambient and driven by a pump with prescribed mass flow.Results:
| output | explanation | formula | actual steady-state value |
| dTSource | Source over Ambient | dtCoolant + dtToPipe | 20 K |
| dTtoPipe | Source over Coolant | Losses / ThermalConductor.G | 10 K |
| dTCoolant | Coolant's temperature increase | Losses * cp * massFlow | 10 K |
