Combustion oscillation characteristics of a supersonic ethylene jet flame using high-speed planar laser-induced fluorescence and dynamic mode decomposition

Energy, 2021
Flame dynamics and combustion oscillation are complex problems in propulsion systems. In this study, the combustion oscillation characteristics of a supersonic ethylene jet flame in a hot coflow were investigated utilizing a 5 kHz high-speed hydroxyl ...

Data-driven three-dimensional super-resolution imaging of a turbulent jet flame using a generative adversarial network.

Applied Optics, 2020
Three-dimensional (3D) computed tomography (CT) is becoming a well-established tool for turbulent combustion diagnostics. However, the 3D CT technique suffers from contradictory demands of spatial resolution and domain size. This work therefore reports a
