Detonation diffraction and re-initiation in hydrogen–oxygen mixture with concentration gradients

Key Points

• Detonation diffraction occurs in hydrogen-oxygen mixtures with concentration gradients, impacting explosive behavior.
• Key evidence shows a complex interaction of reactive flow patterns and explosive wave propagation in mixed gases.
• Observational analysis characterizes the behavior of detonation and re-initiation under varied concentration gradients.
• Findings suggest that understanding these interactions may enhance safety and efficiency in combustion applications.
