Abstract:

The methodology for formulating aviation kerosene surrogate fuels was developed based on enriching combustion chemical property parameters, and presenting accurate computational method for mixture fuel property parameters. Moreover, under the conditions of initial pressure of 0.1 MPa, initial temperatures of 420 K and 460 K, the laminar flame speeds of the real HEF kerosene were measured using the constant-volume combustion bomb experiment. Depending on the methodology, the HEF kerosene surrogate fuel model, consisting of 65% n-dodecane/10% n-tetradecane/25% decalin (mole fraction), was presented. Sufficiently validated results indicated that in both physical and combustion chemical properties, the surrogate fuel models have high similarity with the real HEF kerosene. The present surrogate fuel model and experimental data provide a foundation for the development and validation of the chemical mechanism.
