About the lecture:
Clean future fuels can exhibit wide variance in ignitability and combustion characteristics. Consequently, there is a need for novel ignition strategies to achieve reliable and efficient combustion of low and zero-carbon fuels in future internal combustion engines. Based on this motivation, the first half of this talk will focus on establishing the basics and need for advanced ignition strategies followed by showcasing the potential of integrating optical and metal engine experiments, computational fluid dynamics, and machine learning to develop fuel-flexible Ignition-Assisted combustion technology for sustainable low-carbon fuels. The second part of the lecture will highlight the need and potential of advanced ignition approaches for zero-carbon fuels such as hydrogen and ammonia. This final section will cover technologies such as hot-surface pilot ignition and reactivity-controlled compression ignition for zero-carbon fuels based on high-fidelity numerical simulations. The concluding remarks will summarize future research directions for robust and efficient combustion of future clean fuels.
