Hydrogen as an energy carrier is a very promising alternative fuel in the future. Accidental
hydrogen explosions remain one of the major concerns in hydrogen energy utilization and …

Various experimental and DNS data show that premixed combustion is affected by the
differences between the coefficients of molecular transport of fuel, oxidant, and heat not only …

The development and evolution of tulip and distorted tulip flames in closed channels were
simulated by solving the fully compressible reactive Navier–Stokes equations using a high …

High-speed schlieren photography, pressure records and large eddy simulation (LES)
model are used to study the shape changes, dynamics of premixed flame propagation and …

In this study, the explosive characteristics of non-uniform methane-air mixtures in a 1.5 m
half-opened vertical channel with ignition at the open end were experimentally studied. The …

Numerical simulations were performed to study the effects of pressure waves on the
evolution and stability of flames propagating in tubes. The model is the fully compressible …

This work aims to investigate the influences of an obstacle on the deflagration behaviors of
premixed liquefied petroleum gas (LPG)-air mixtures. Experiments were conducted in a …

The experimental results that are the subject of this communication provide high-speed
schlieren images of the closed-tube flame shape that has come to be known as the tulip …

The behaviors and shape changes of premixed hydrogen–air flames at various equivalence
ratios propagating in half-open and closed horizontal ducts are experimentally investigated …

The dynamics of a distorted tulip flame in a closed duct has been experimentally and
numerically investigated [Xiao et al., Combust. Flame 159 (2012) 1523–1538]. In the present …
