While the burning properties of flames have been extensively investigated at pressures below and above ambient, it is almost impossible to find any data for temperatures below 290 K. The PAC group investigates flame extinction by quenching on cryogenic surfaces and flame properties under cryogenic conditions
Compared to classical constant volume or constant pressure combustion, the detonation regime of combustion has the potential to increase the efficiency of engines and contribute to the reduction of carbon emission in the atmosphere. However, the development of efficient and reliable detonation engines is challenging and several issues need to be addressed.
One promising strategy to integrate the energy from renewable sources in the grid is by using hydrogen carrier fuels burned in gas turbines. Power plants are generally burning fossil fuels like natural gas, coal, diesel, heavy fuel oil, etc. Replacing these traditional fuels by hydrogen carriers will be challenging.
The general idea of plasma-assisted combustion is to enhance combustion by mean of an electric field, with minimal energy and pollutant penalty. The electrical energy input should be negligible compared to the thermal energy released by combustion or, alternatively, the electrical energy input should be less than the thermal energy saved.
