We have capabilities to generate detailed and tailored reduced chemical kinetic mechanisms for thermal oxidative degradation for a broad range of liquid hydrocarbons including conventional aviation fuel, alternative aviation fuel, blend of alternative and conventional as well as diesel and lubricants. The resultant mechanisms are validated against the fundamental/small scale test rigs where the impact of complex fluid flow and heat transfer characteristics are minimised. Subsequently, these mechanisms are used with CFD codes in order to simulate real time formation of surface carbonaceous deposits in engine representative conditions.
We are also developing models for predicting seal swell under different test conditions and fuel compositions.
Research group members have also been working on hydrogen / hybrid combustion, with an aim to reduce NOx emissions and increase flame stability limits. Work is also being done to reform hydrocarbon fuel, subsequently capture the carbon and then combustion of hydrogen rich mixture, with an aim to capture carbon before combustion and reduce NOx emissions as well.
