Abstract

The bridge to carbon neutrality within propulsion and power systems will undoubtedly involve continued improvements in fuel efficiency, which has an inverse relationship with emissions. High-pressure combustion enables thermodynamic cycle benefits including increased fuel efficiency. As such, it is expected that the future ultralow emission engine concepts, regardless of fuel, will require improved understanding of combustion chemistry and device performance at elevated pressures. For the purposes of this text, we will define high pressure as greater than 20 bar. This represents the domain of most modern gas turbines, reciprocating engines, and rockets. It should be noted that future ultraefficient engine concepts have been proposed with extreme combustion pressures in the hundreds of bar. Among other experimental and modeling challenges at high combustion pressures, a critical gap persists in combustion diagnostics. Here, we elaborate on challenges, recent progress, and future needs in high-pressure combustion diagnostics.
