Experimental Characterization of the Thermodynamic Properties of Diesel Fuels Over a Wide Range of Pressures and Temperatures

Abstract: The influence of pressure and temperature on some of the important thermodynamic properties of diesel fuels has been assessed for a set of fuels. The study focuses on the experimental determination of the speed of sound, density and compressibility (via the bulk modulus) of these fuels by means of a method that is thoroughly described in this paper. The setup makes use of a common-rail injection system in order to transmit a pressure wave through a high-pressure line and measure the time it takes for the wave … Show more

“…The considered fluid consists of a European standard winter diesel fuel. The density was characterized by the authors at atmospheric pressure as a function of temperature (ranging from 273 K to 373 K) using a standard hydrometer, taking into account the considerations stated by the ASTMD1298 procedure [30] (including those corresponding to the calibration procedure [31]). The accuracy of the hydrometer was determined to be ±5 x 10 -4 kg/m 3 .…”

“…In order to establish the variations of the fuel density with the pressure, speed of sound measurements were also performed at different pressures (up to 20 MPa) and temperatures (from 300 K to 353 K) following the methodology established in [31]. The maximum deviations reported during the calibration of the facility were 1.24% over the expected values.…”

“…Knowing the distance between these two transducers, it is possible to characterize the speed of sound by measuring the time lapse that the pressure perturbation takes to travel to one sensor to another. More information about the experimental setup can be seen in [45]. Figure 2 shows the results from the fuel characterization for a range of 0.1-300 MPa in pressure and 300-400 K in temperature, which are representative of the usage of diesel fuel in advanced common rail systems.…”

“…3highlighted the need of knowing the evolution of ρ, b and c p with respect to the pressure and temperature in order to determine the theoretical temperature change after an isenthalpic expansion. Speed of sound measurements at different pressures and temperatures were carried out in order to determine the density following the procedure already validated by the authors [21] [33]. The thermal expansion coefficient, b, was then determined through Eq.…”
