Investigation of shock-turbulence-chemistry interaction in detonation phenomena: enhancement of numerical modelling

Project Details


Gas-fired power plants are going to play a key role in the support of intermittent renewable energy sources in the future.
In recent years, detonation combustion concepts were investigated aiming to augment the thermal efficiency and reduce emissions production. Rotating Detonation Engines show great promise in this regard, thanks to the quasi-steady thrust, lighter structure and easier scalability. Experience, however, shows that there is a significant gap between the current numerical predictions and the available experimental results, concerning the detonation front stability.
This discrepancy can be due to the lack of physical understanding of the shock-turbulence-chemistry interaction and therefore, to its accurate modelling.

The proposed research contributes then to the enhancement of the detonation combustion modelling by using a segregated approach. The physical process of the turbulent-shock and turbulencechemistry interaction will be investigated and validated independently and then coupled together to provide a unique framework. Finally, the validation against experimental data will assess the predictive capabilities of this innovative model. As outcome, this research will provide fundamental knowledge to advance the current detonation combustor design towards the energy transition
