Modeling of equilibrium combustion of kerosene by a mixture of gaseous hydrocarbons

It is demonstrated that the composition and parameters of state of the gas formed in the course of equilibrium combustion of aviation kerosene in air can be modeled by means of determining the same quantities for a certain mixture of hydrocarbon fuels. The latter can be a mixture of identical amounts of methane and acetylene. The equilibrium composition calculated for the model mixture exactly coincides with the composition of kerosene combustion products for identical values of pressure (or density), temperature, and oxidizer-to-fuel ratio. Combustion of kerosene and the model mixture in a constant-pressure (or constant-density) mode can ensure satisfactory agreement between the temperatures of the final products and their compositions if air with a lower-than-normal fraction of oxygen is used as an oxidizer.
