Combustion at high pressures has the potential to increase the efficiency and usability of jet engines in the presence of high moisture. However, not a lot of research has been done in the domain of high pressure combustion owing to various challenges of performing experiments as well as simulations in these conditions. The studies that exist mostly explore the combustion of fuels such as methane and its hydrates. Also, which chemical reactions are the most dominating reactions in these cases hasn't been explored much. In this work, combustion of a proper jet engine fuel, JP-10 is analyzed under high pressures in the presence of dry air as well as moisture by plotting temperature and axial velocity profiles in a 1-dimensional cross-flow diffusion flame setting using Cantera's open source code. It is found that increasing pressure increases the extinction limit for the fixed amount of JP-10 being burnt in air. This finding proves that for given a high pressure device, the combustion of jet fuel can take place even if it contains higher amounts of moisture, hence, increasing its application range and usefulness, especially in extreme environmental situations. To determine the most dominant chemical reactions, sensitivity analyses are carried out for the various cases of pressure for both dry fuel as well as with moisture, near the extinction limits of the corresponding pressures. Hence, showing that an increase in pressure plays a significant role in altering the pathway that the combustion chemical reaction is following, proving that the role of the chemistry of the fuel cannot be ignored while developing high pressure combustion devices.
