Although delayed detonation models of thermonuclear explosions of white dwarfs seem promising for reproducing Type Ia supernovae, the transition of the flame propagation mode from subsonic deflagration to supersonic detonation remains hypothetical. A potential instant for this transition to occur is the onset of the distributed burning regime, i.e. the moment when turbulence first affects the i...

The experimental study of the oxidation of cyclohexane has been performed in a jet-stirred reactor at temperatures ranging from 500 to 1100 K (low- and intermediate temperature zones including the negative temperature-coefficient area), at a residence time of 2 s and for dilute mixtures with equivalence ratios of 0.5, 1, and 2. Experiments were carried out at quasi-atmospheric pressure (1.07 ba...

Detailed models of the explosion of a white dwarf, which include self-consistent calculations of the light curve and spectra, proved a link between observational quantities and the underlying explosion model. These calculations assume spherical geometry and are based on parameterized descriptions of the burning front. Recently, first multidimensional calculations for nuclear burning fronts have...

A reaction-diffusion model for the propagation of an idealized forest fire is revisited to include the effect of wind on the speed of propagation. We study the existence of one-dimensional travelling wave solutions. When the wind velocity is zero or when the wind blows from the burning region, the existence and uniqueness of the travelling wave is proved. In the case when the wind blows into th...

In the last decade, several fires and explosions caused by Li-ion batteries (LIBs) have been reported. This can be attributed to thermal runaway catastrophic failures of LIBs that release combustible gases, which when mixed with air lead fires. To address this explosion hazard, we determine laminar burning velocity (LBV) three gas compositions associated failure a pseudo (simplified) in 20-L sp...
