Pressure Increase

Enforce constant pressure increase

Description

The Pressure Increase component is a two-port thermal-fluid component that establishes a pressure increase from port $a$ to port $b$.  The temperature and enthalpy of the medium are not changed. When the usePressureIncreaseInput boolean parameter is false, the pressure increase is set by the component parameter ${\mathrm{Δ}}_{}{p}_{\mathrm{const}}$, otherwise the pressure increase is set by a signal input.

 ${Q}_{\mathrm{flow}}=0$

Connections

 Name Description ${\mathrm{flowPort}}_{a}$ Thermal-fluid flow port ${\mathrm{flowPort}}_{b}$ Thermal-fluid flow port ${\mathrm{Δp}}_{\mathrm{input}}$ Signal input; present when the usePressureIncreaseInput parameter is true
