Review of Combustion Characteristics and Reaction Mechanism Construction of RP-3 Aviation Kerosene

At present,the numerical simulation calculation of the multi-step combustion reaction mechanism of coupled aviation kerosene had attracted the attention of scholars,and the construction of the combustion reaction mechanism had become a research focus.The experimental rules on the selection of aviation kerosene surrogate fuel,the construction and simplification of chemical reaction kinetic model,the ignition delay time and laminar burning velocity were introduced in detail.According to the research progress abroad,it was pointed out that the study of the combustion mechanism of domestic RP-3 aviation kerosene should start from the basic research and the related research should be carried out in a comprehensive,multi-dimensional and stereoscopic way in China in order to enrich the relevant research results and promote the high quality development of aeroengine.These research mainly included the establishment of the chemical kinetics model of domestic RP-3 aviation kerosene,the basic experimental studies and the study of model combustor of aviation kerosene and simulated alternative fuels under the conditions of low temperature and high pressure.
