Thermophysical properties of Normafluid (ISO 4113) over wide pressure and temperature ranges

This paper presents new experimental results for Normafluid ISO 4113. Vapor pressures of Normafluid were measured from 0.001 kPa to 27 kPa and from 273 to 463 K, using a static apparatus. The experimental vapor pressures were smoothed using the Antoine equation. Air solubility in the fuel at 288 K, 298 K and 308 K and up to 0.8 MPa was also determined. Isobaric thermal expansivitites of Normafluid were determined over the temperature range from 273.15 K to 423.15 K at pressures up to 200 MPa using scanning transitiometry; therefrom thermodynamic relations were used to obtain the isobaric specific heat capacities, specific volumes, isothermal compressibilities, isentropic compressibilities and isentropic bulk modulus over wide pressure and temperature ranges.
