Oil Linear Density model¶
The linear density model requires the input of a reference density, pressure and temperature, and compressibility and expansion coefficients. See example below:
EOS OIL DENSITY LINEAR REFERENCE_VALUE 833.5d0 !den0 [kg/m3] PRES_REF_VAULE 5.516d6 ![Pa] TEMP_REF_VALUE 94.8 ![°C] COMPRESS_COEFF 1.672d-7 !C [kg/m3/Pa] THERMAL_EXPANSION_COEFF 0.0d0 !E [kg/m3/°C] END ENTHALPY LINEAR_TEMP 1.d3 !c oil [J/kg/°C] VISCOSITY CONSTANT 0.987d-3 END
