VolumeFlow

Enforces constant volume flow

    VolumeFlow

Library

Modelica/Thermal/FluidHeatFlow/Sources

Description

Fan resp. pump with constant volume flow rate. Pressure increase is the response of the whole system.

Coolant's temperature and enthalpy flow are not affected.

Setting parameter m (mass of medium within fan/pump) to zero leads to neglect of temperature transient cv*m*der(T).

Thermodynamic equations are defined by Partials.TwoPort.
