My research focuses on mitigating the environmental impact of the aviation sector as well as ensuring the safe operation of novel propulsion and battery technologies. Currently, I am actively pursuing the following research problems:
Vortex breakdown phenomenon in swirl-stabilized combustors: A central recirculation zone is used to stabilize the flame in aviation and power gas turbine combustors. Depending on the specific combination of the swirler and combustor, the recirculation zone may be of the open (conical mode) or closed (bubble mode) type. This study will use numerical and experimental tools to study the transition and hysteresis between these modes and their impact on NO emissions from the combustor.
Flashback phenomenon in high-hydrogen combustors: The risk of flame flashback is aggravated as the hydrogen content in the fuel is increased in a premixed combustor. Characterizing the influence of various input parameters (e.g., swirl and turbulence intensity) on the flashback boundary is essential to ensure the safe operation of the combustor. This study will experimentally and numerically explore how the input parameters influence the flashback boundary in a lean-premixed hydrogen flame.
Inhibition of hydrogen detonation using chemical inhibitors: Detonation is a type of combustion where a reactive front couples with a normal shock, leading to vigorous burning and a large pressure rise. I am investigating the influence of chemical additives that can decouple the shock-flame complex, thus weakening a detonation into a deflagration. This is a numerical study using chemical kinetic tools and commercial CFD software.
