The effect of temperature and pressure on thermodynamic properties of diesel and biodiesel fuels

The current work focuses on the study of the influence of pressure and temperature on three important thermodynamic properties: speed of sound, compressibility and density of common diesel fuels. The sample fuels studied were conventional diesel (Repsol Elite), Rape Methyl Ester (typical bio-diesel...

Zusammenfassung:	The current work focuses on the study of the influence of pressure and temperature on three important thermodynamic properties: speed of sound, compressibility and density of common diesel fuels. The sample fuels studied were conventional diesel (Repsol Elite), Rape Methyl Ester (typical bio-diesel used in Spain) and a fuel used especially for winter season (Arctic). Speed of sound and densities has been determined experimentally. The third property, bulk modulus, has been calculated from the other two. Speed of sound measurements have been carried out in wide range of temperatures (298
