Abstract

Abstract

Based on the physical phenomena of hydrogen flame acceleration, the present paper introduced the σ criteria for hydrogen security analysis of flame acceleration. From the quench/re-ignition of flammable gas mixture theory, the flame acceleration criteria at elevated temperatures and pressures was been put forward by considering the effect of laminar flame velocity from pressures and been validated by hydrogen defragration and detonation experiments at elevated temperatures and pressures.
