Supersonic mixing and combustion control using streamwise vortices

Thrust augmentation optimization through supersonic after-burning in scramjet engine nozzles via surrogate-assisted evolutionary algorithms

“…This is assumed to be attributed to inadequate diffusion between the fuel jet and crossflow which is a result of the highly compressible nature of the supersonic/hypersonic crossflow. Further, the axisymmetric nature of the model ignores streamwise vortices which would likely contribute to the enhancement of mixing [35].…”

Mathematical Modeling and Analysis of Different Type of Fuel Injector in Scramjet Engine Using CFD Simulation in Fluent

“…A decent tight field blending can be accomplished by divider infusion. Then again transverse infusion frameworks cause a huge blockage of the stream bringing about irreversibility's because of stunning waves and push misfortunes [27]. Another concern is the case that the entrance of the fuel plane may be inadequate for genuine size combustors.…”

Large-Eddy Simulation of Fuel Mixing Using Streamwise Vortices in a Supersonic Flow

“…The fuel is injected parallel to the main airflow into each streamwise vortex core. Sunami et al 6) revealed by the combustion tests that the AW strut injector had superior mixing and combustion abilities to a generic strut injector without streamwise vortices. They also investigated the flow structure downstream of the AW strut using Mie scattering 7) and OH-PLIF 8) .…”

“…This indicates that the use of streamwise vortices is effective for a supersonic mixing. Many researchers have developed fuel injector designs actively introducing streamwise vortices 5,6) . Sunami et al 6) proposed 'alternating-wedge (AW) strut injector'.…”
