Oil linear enthalpy¶

The linear oil enthalpy model relates the enthalpy with temperature only, using the oil specific heat capacity. An example is given below:

EOS OIL
DENSITY CONSTANT 734.29d0 !kg/m3
ENTHALPY LINEAR_TEMP 1.d3 !c oil [J/kg/°C]
VISCOSITY CONSTANT 0.987d-3 !
END


The mathematical expression of the model is represented below:

$h_{\mbox{oil}} =c_{\mbox{oil}} T,$

where:

$\begin{split}\begin{split} &h_{\mbox{oil}} &= \mbox{oil Enthalpy [J]}\\ &c_{\mbox{oil}} &= \mbox{oil specific heat capacity [J/kg/°C]}\\ &T &= \mbox{temperature [°C]} \end{split}\end{split}$

Units cannot be specified, therefore the oil specific heat must be entered in the units prescribed above.
