The early stages of hydrogen–air and methane–air flame dynamics the development evolution tulip flames in closed tubes various aspect ratios a semi-open tube are studied by solving fully compressible reactive Navier–Stokes equations using high-order numerical method coupled to detailed chemical models for stoichiometric hydrogen/air methane/air mixtures. use adaptive mesh refinement (AMR) provides adequate resolution reaction zone, pressure waves, flame–pressure wave interactions. purpose this study is gain deeper insight into influence kinetics on combustion regimes leading formation its subsequent evolution. simulations highlight effect thickness, velocity, order intensity rarefaction generated during deceleration phase, which principal physical mechanism formation. obtained results explain most experimentally observed features formation, e.g., faster with shape compared slower flames.
