Compared with traditional deflagration-based systems, detonation-based propulsion
systems offer significant potential benefits in terms of efficiency and specific impulses in the …

Standing oblique detonation is a unique pressure-gain combustion phenomenon for
hypersonic ramjet propulsion, and its research has been related with supersonic combustion …

During this anthropocentric period, sustainable energy supply and climate changing could
be a main source of problem for human being. Scientists believe that the ratio of climate …

Hypersonic airbreathing propulsion is one of the top techniques for future aerospace flight,
but there are still no practical engines after seventy years' development. Two critical issues …

In this study, wall roughness is generated by inserting a Shchelkin spiral with different wire
diameter (δ) and pitch (L s). Roughness is defined as the ratio δ/L s. The effect of tube wall …

In this paper, detonation limits in stoichiometric methane-oxygen mixtures with varying tube
inner diameter and initial mixture pressure were investigated. Detonations in tubes with …

At the near-limit conditions, the behavior of detonation propagation manifests unstable
modes; those modes are classified into three types, ie, steady mode, fluctuation mode and …

An understanding of oblique detonation waves (ODWs) has inherent research value for high-
speed compressible reacting flow and hypersonic propulsion. In this paper, the interactions …

Many direct numerical simulations of spherical hot spot auto-ignitions, with different fuels,
have identified different auto-ignitive regimes. These range from benign auto-ignition, with …

The feasibility of mode control in rotating detonation engine is investigated through
regulating the global equivalence ratio during the test under different air mass flow rates …
