modelR410A_dSpecificVolumeVap_pT
Validation of the derivatives of the specific volume with regards to p and T
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
Validation case for evaluation of derivatives of the Martin-Hou equation of state with regards to pressure and temperature.
The analytical implementation of derivatives is compared to a numerical evaluation of the derivatives.
