Journal of the Fuel Society of Japan, 1971 The combustion in propulsion engines or industrial furnaces is never perfectly smooth and is usually accompanied with random fluctuations in the combustion rate as well as in pressure and velocity. When the pressure fluctuation becomes in phase with the fluctuation in the heat release rate of combustion, the fluctuation will develop into the organized ...

Effects of swirl on intermittency characteristics in turbulent non-premixed flames [PDF]
, 2012 Swirl effects on velocity, mixture fraction and temperature intermittency have been analysed for turbulent methane flames using LES. The LES solves the filtered governing equations on a structured Cartesian grid using a finite volume method, with ...

Supersonic Combustion Mode Analysis of a Cavity Based Scramjet
Aerospace, 2022 Since flame stability is the key to the performance of scramjets, scramjet combustion mode and instability characteristics were investigated by using the POD method based on a cavity-stabilized scramjet. Experiments were developed on a directly connected

Advanced Materials, EarlyView.Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

Effects of LOX Particle Diameter on Combustion Characteristics of a Gas-Liquid Pintle Rocket Engine
International Journal of Aerospace Engineering, 2020 LOX/GCH4 pintle injector is suitable for variable-thrust liquid rocket engines. In order to provide a reference for the later design and experiments, three-dimensional numerical simulations with the Euler-Lagrange method were performed to study the ...

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels
Advanced Materials Interfaces, EarlyView.When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...
