Volume Flow

Assign ambient temperature and pressure

Description

The Volume Flow component is a two-port thermal-fluid component that establishes a set volume flow.  The temperature and enthalpy of the medium are not changed. When the useVolumeFlowInput boolean parameter is false, the volume flow is set by the component parameter ${V}_{\mathrm{flow}}$, otherwise the flow is set by a signal input.

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