The invention relates to the technical field of
aviation fuel, and discloses a
combustion characteristic rapid prediction method suitable for sustainable
aviation fuel, comprising the following steps: step 1, acquiring fuel molecules of the sustainable
aviation fuel and fuel composition data thereof; two-dimensional structure data and
combustion test data of the fuel molecules are obtained, and then a fuel molecule
database is formed; 2, on the basis of the two-dimensional structure data, a
quantum chemistry calculation method is adopted, and basic reaction descriptors of corresponding
hydrocarbon molecules are obtained; based on
combustion test data, screening to obtain a physical descriptor; 3, a
correlation analysis method is adopted, and target descriptors are obtained through screening; step 4, performing multi-
model prediction based on the target descriptor in combination with combustion conditions; and calculating the accuracy index of each model, and screening to obtain an optimal model to predict the combustion characteristics. According to the method, the combustion characteristics of the sustainable
aviation fuel can be accurately and efficiently predicted, and the prediction reliability is high.
