Simulation of Laser-Induced Plasma Ignition in a Hypersonic Crossflow

“…In this range unsteady flame effects are observed with local ignition and extinction [13]. This new regime classification model should be considered tentatively as limited research has been performed into defining the regime boundaries ( & ) in supersonic flow conditions [10]. Furthermore, using Williams fundamental simplification, characterising all chemistry interactions with the chemical timescale [7], is a poor approximation of the complex chemical interactions existing in non-premixed turbulent combustion.…”

“…The scramjet designs examined in this report rely on hydrogen (H2) as fuel. When combustion between the hydrogen and oxygen (O2) occurs, a by-product called hydroxyl (OH) is produced and not re-consumed [10]. The OH radical occupies the reaction zone and can be illuminated and photographed by using a technique known as Planar Laser Induced Fluorescence (PLIF).…”
