Abstract
Expanding on earlier viscosity measurements of rocket propellants from 293 K to 373 K at atmospheric pressure, the viscosity of rocket propellant RP-2 was measured from 270 K to 450 K with pressures to 137 MPa. The instrument was an oscillating piston viscometer, modified and recalibrated at NIST with dodecane as a reference fluid over the full temperature and pressure range. Based on the recalibrations, the repeatability of the measurements was found to be approximately 3 % while the uncertainty of the instrument is estimated at 5 %. The measured viscosities of RP-2 were compared with values calculated with a five-component surrogate mixture model developed at NIST Boulder. The experimental data have a stronger pressure dependence than the mixture model and are up to 29 % higher at high compressions.Citation
