A new endothermic hydrocarbon fuel EHF-851 was proposed for thermal management of advanced aircraft, with a higher heat sink compared to JP-10 and lower than JP-7. The pyrolysis of EHF-851 was investigated under sub- and super-critical conditions, showing significant inhibition of pyrolytic cokes formation due to the hydrogen donor effect of decalin.
A new endothermic hydrocarbon fuel with density of 0.851 g/cm3 (EHF-851) was proposed taking account of the energy density and heat sink of hydrocarbon fuels for the thermal management of advanced aircraft. Sub- and super-critical pyrolysis of EHF-851 was investigated by the electrically heated tube test at 650-750 ?C under 0.7?6.0 MPa. The effect of operation parameters (flow rate, pressure and fuel temperature) on the heat sink and detailed pyrolysis products were presented. The heat sink of EHF-851 is 3.32 MJ/kg at 750 ?C (6.0 MPa, 2.67 g/ s), which is 25 % higher than that of JP-10 but 8 % lower than that of JP-7. The formation of pyrolytic cokes was significantly inhibited attributed to the hydrogen donor effect of decalin in the fuel.
