| Paper description |
tA two-capillary method based on the Hagen–Poiseuille theory was proposed for on-line measurements ofdynamic viscosity of hydrocarbons at high temperatures and high pressures. A two-capillary viscometerwas designed and proved to be applicable to the viscosity measurements in a mini-tube. The standarduncertainty of dynamic viscosity measurements is identified as (2.22–5.28) % (coverage factor k = 2). N-heptane, n-octane and their binary mixture were tested respectively in the calibration experiments ofthe viscometer. Results showed that the measured maximum relative deviations of all substances wereall within 2% and the average absolute deviations were within 0.72%. Finally viscosities of a kerosenekind hydrocarbon fuel were measured using the two-capillary viscometer at temperature from (303.2 to513.2) K and supercritical pressures of (3.00 and 4.00) MPa. |
