isentropicEnthalpy

Return isentropic enthalpy

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This function computes an isentropic state transformation:

  1. A medium is in a particular state, refState.
  2. The enthalpy at another state (h_is) shall be computed under the assumption that the state transformation from refState to h_is is performed with a change of specific entropy ds = 0 and the pressure of state h_is is p_downstream and the composition X upstream and downstream is assumed to be the same.

Inputs (2)

p_downstream

Type: AbsolutePressure (Pa)

Description: Downstream pressure

refState

Type: ThermodynamicState

Description: Reference state for entropy

Outputs (1)

h_is

Type: SpecificEnthalpy (J/kg)

Description: Isentropic enthalpy
