Helicity in Supercritical O₂/H₂ and C₇H₁₆/N₂ Mixing Layers

This report describes a study of databases produced by direct numerical simulation of mixing layers developing between opposing flows of two fluids under supercritical conditions, the purpose of the study being to elucidate chemical species-specific aspects of turbulence, with emphasis on helicity. The simulations were performed for two different fluid pairs — O2/H2 and C7H16/N2 — at similar values of reduced pressure.
