Hydrogen Jet Flame Global Instabilities and Their Control Using Suction
摘要
This study employs large-eddy simulations (LES) to explore how counter-current co-axial flow influences global instability in hydrogen jet flames. It reveals that the critical velocity ratio for triggering global instability falls between 0.1 and 0.2. Additionally, applying strong suction ( \(I = 0.2\) ) around the fuel jet can effectively change the position and size of the flame.
