Methodology to generate decoupled real fuel surrogates for 3-dimensional spray and combustion modeling in engine applications

A method to determine a composition of a surrogate fuel, the method comprising:

• determining, using a gas chromatography device communicably coupled to a computing device, a plurality of gas properties and a plurality of liquid properties of a sample fuel;
• receiving, with a processor of the computing device, a plurality of fuel targets defining desired combustion parameters of the surrogate fuel;
• assigning, with the processor of the computing device, a palette of liquid fuel species based on the plurality of liquid properties of the sample fuel, and assigning a palette of gas fuel species based on the plurality of gas properties of the sample fuel;
• determining, with the processor of the computing device, a liquid surrogate formulation from the palette of liquid fuel species, and determining a gas surrogate formulation from the palette of gas fuel species;
• outputting, with the processor of the computing device, a proportional composition of chemical elements forming the surrogate fuel based on the liquid surrogate formulation and the gas surrogate formulation, and
• formulating the surrogate fuel with a gas processing facility based on the proportional composition of the chemical elements.
