Abstract: Since batteries do not seem capable of reaching the charging times and energy densities required in some applications, a zero-carbon energy system will contain significant contributions from gaseous or liquid renewable fuels whose energy is extracted by combustion. Some recent developments on the turbulent combustion of ammonia and hydrogen will be presented to highlight their complex chemistry and interactions with the fluid motions that must be harnessed in order to produce the next-generation propulsion devices and heating systems. Examples from power generation, aviation, and maritime propulsion will be given with a focus on parasitic emissions and flame structures. The talk will also include comments on how the models needed for novel engine development can be used to great advantage for wildfires amplified by climate change.
