PressureIncrease
Enforces constant pressure increase
Library
Thermal/FluidHeatFlow/Sources
Description
Fan resp. pump with constant pressure increase. Mass resp. volume flow 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.
