Density and Speed of Sound Measurements of Jet A and S-8 Aviation Turbine Fuels



Stephanie L. Outcalt, Arno R. Laesecke, Malte B. Freund


The density and speed of sound were measured for three compositions of aviation jet fuel A, and a synthetic fuel (S-8) derived from the Fischer-Tropsch process. Measurements of density and speed of sound were carried out at ambient pressure (83 kPa) with a rapid characterization instrument from 278.15 K to 343.15 K. Density measurements of the compressed liquids ranged from 270 K to 470 K with pressures to 30 MPa. A total of 529 experimental points are reported. The density measurements are correlated within 0.1 % with a modified Tait equation of state, and adiabatic compressibilities are derived from the density and speed of sound data at ambient pressure.
