In this work, a novel and simple method was put forward to measure the isobaric specific heat capacity forthe kerosene RP-3 with a flow-calorimeter at the conditions of high temperature and high pressure. Basedon the energy conservation principle, the formula for heat capacity was derived and its measurementwas realized by the convective mixing method between the hot and cold fuel. Taking the precision of theinstrument and the error transfer into account, the relative expanded uncertainty of this method wasacquired of about +- 6.38% (coverage factor k = 2). Meanwhile, the accuracy and reliability were verified bythe standard material of water and n-decane. In the temperature range from (296.2 719.0) K and underpressure range from (2.4 4.0) MPa, the measurement for the kerosene RP-3 was carried out and theexperimental observations were compared and agreed well with the published data. At last, an empiricalcorrelation relationship of heat capacity due to the temperature and pressure was presented by usingGarg s model with the measured experimental data.
