Design of a Flow Calorimeter for Hydrocarbon Fuel at Temperatures from (330 to 900) K and Pressures up to 6.0 MPa
2015
The isobaric specific heat capacity of a kerosene type hydrocarbon fuel was measured online using a flow calorimeter, which was based on the energy conservation theory. The test temperatures covered from (330 to 900) K and operating pressures changed from (1.96 to 4.93) MPa. The isobaric specific heat capacity data have an expanded relative uncertainty of 2.54 % with a coverage factor of 2. The reliability and accuracy of the flow calorimeter measurement was verified by the water, n-hexane, and binary mixtures of n-heptane + n-octane and methanol + acetone, respectively. Finally, the isobaric specific heat capacities of a type of endothermic hydrocarbon fuel were measured and Cp–T diagrams were plotted at sub- and supercritical pressure.
