Experimental and numerical studies are carried out to construct reliable surrogates that can reproduce aspects of combustion of JP-8 and Jet-A. Surrogate fuels are defined as mixtures of fuels that can mimic the behavior of the real fuels. The study aims to develop a comprehensive understanding of the combustion process and to identify the key factors that influence the combustion behavior. The results of the study can be used to improve the design and optimization of combustion systems, leading to more efficient and environmentally friendly engines.
