“…strut type, etc.) of providing almost complete premixing of fuel with air at supersonic speeds have been proposed and analysed in a number of studies (Cambier, Adelman & Menees 1990;Menees et al 1991;Valorani, Di Giacinto & Buongiorno 2001;Alexander, Sislian & Parent 2006). For liquid fuels, the complexity of multiphase flows presents also another hurdle (Ren et al 2018(Ren et al , 2019b.…”

Recent developments in Pressure Gain Combustion (PGC) technology have demonstrated its ability to achieve higher thermal efficiencies and lower carbon emissions as compared to conventional gas turbine counterpart working in Brayton cycle. Ongoing studies suggest the possibility of implementing PGC in aircraft engines by replacing the high-pressure section (HP compressor, combustion chamber and HP turbine) with a PGC system. This, coupled with research on advanced materials and cooling solutions, offers the potential for higher overall gas turbine efficiency and fuel economy, contributing towards emission reduction of the aviation sector. This paper aims at a comprehensive review of PGC technology solutions applied in the area of aero propulsion. Reported background covers the historic as well as ongoing research activities at the component level, the cycle level, and the propulsion application of Pulse Detonation Engine (PDE), Rotating Detonation Engine (RDE), Oblique Detonation Wave Engine (ODWE), Free Piston Composite Cycle Engine (FP-CCE), and wave rotor engines. The analytical, numerical, and experimental research work is reviewed, providing also a comparison of PGC engine conceptual designs with existing gas turbine engines used in aerospace propulsion.

“…2.1.7 shows that the specific impulse decreases as the fuel-air equivalence ratio (higher fuel mass flow) and the free stream Mach number (higher pressure losses) are increased. Here, the fuel re-heat temperature is 1100 k and the free stream dynamic pressure q ∞ is 90 kPa [32]. Sislian et al studied and compared the propulsive characteristics of the hypersonic detonation wave and shock-induced combustion ramjets.…”

WANg For the range of flight Mach number of ODWE, the mixed external-internal supersonic compression (MSC) method is more effective than the internal supersonic compression (ISC) and external supersonic compression (ESC) [32]. The speed of the flow past the intake and ahead of ODW must be at supersonic condition.…”

Detonation is a promising combustion mode to improve engine performance, increase combustion efficiency, reduce emissions, and enhance thermal cycle efficiency. Over the last decade, significant progress has been made towards the applications of detonation mode in engines, such as standing detonation engine (SDE), Pulse detonation engine (PDE) and rotating detonation engine (RDE), and the understanding of the fundamental chemistry and physics processes in detonation engines via experimental and numerical studies. This article is to provide a comprehensive overview of the progress in the knowledge of rotating detonation engine from the different countries. New observations of injection, ignition, and geometry of combustor, pressure feedback, and combustion modes of RDE have been reported. These findings and advances have provided new opportunities in the development of rotating detonation for practical applications. Finally, we point out the current gaps in knowledge to indicate which areas future research should be directed at.
