Assessment of the performance of alternative aviation fuel in a modern air-spray combustor (MAC) [PDF]
, 2008 Recent concerns over energy security and environmental considerations have highlighted the importance of finding alternative aviation fuels. It is expected that coal and biomass derived fuels will fulfil a substantial part of these energy requirements ...

Initiation of the detonation in the gravitationally confined detonation model of Type Ia supernovae
, 2009 We study the initiation of the detonation in the gravitationally confined detonation (GCD) model of Type Ia supernovae (SNe Ia). Initiation of the detonation occurs spontaneously in a region where the length scale of the temperature gradient extending ...

Results of 1/4-Scale Experiments. Vapor Simulant And Liquid Jet A Tests [PDF]
, 2000 A quarter-scale engineering model of the center wing tank (CWT) of a 747-100 was constructed. This engineering model replicated the compartmentalization, passageways, and venting to the atmosphere.

The role of chemistry in the oscillating combustion of hydrocarbons : an experimental and theoretical study [PDF]
, 2020 The stable operation of low-temperature combustion processes is an open challenge, due to the presence of undesired deviations from steady-state conditions: among them, oscillatory behaviors have been raising significant interest.

Laser ignition of methane jets in homogenous and isotropic turbulence
2018 AIAA Aerospace Sciences Meeting, 2018 The ignition of a pulsed methane jet by a laser-induced spark was investigated in air under the influence of homogenous and isotropic turbulence with zero mean flow. In this way, the contribution of the turbulent velocity fluctuations of the environment can be isolated from the mean flow component.

On the features of diffusion combustion of hydrogen microjets [PDF]
E3S Web of ConferencesThis paper presents the results of an experimental investigation of the diffusion combustion scenario of a round hydrogen microjet flowing from a cylindrical thin-walled micronozzle with a diameter of 200 μm when ignited near and at any distance from the
