Fuel oxidation studies are crucial for improving combustion efficiency, reducing emissions, and developing alternative fuels. They help design cleaner systems, minimize pollutants, and enhance engine performance, while supporting climate goals and reducing reliance on fossil fuels

This research project investigates the oxidation and combustion properties of various fuels and fuel surrogates, with a particular focus on low-temperature oxidation chemistry. Through a series of experimental and kinetic modeling studies, the project examines methane (CH₄), compressed natural gas (CNG), n-heptane, cyclohexane, p-cymene, hydrogen sulfide (H₂S), oxymethylene ethers (OMEn), and other bio-aromatic and fossil-derived fuels. The studies utilize a wide range of experimental setups including shock tubes, rapid compression machines (RCMs), jet-stirred reactors (JSRs), and laser absorption techniques to measure ignition delay times, flame speeds, and species concentration profiles under different pressures, temperatures, and fuel mixtures. The project includes detailed chemical kinetic modeling for these fuel oxidation pathways, with a focus on understanding complex reactions, such as third oxygen addition, NOx effects, and sulfurous species interactions. The experimental data is used to validate and refine kinetic models, providing more accurate predictions of combustion behavior.
