A Common Explosion Mechanism for Type Ia Supernovae [PDF]
, 2007 Type Ia supernovae, the thermonuclear explosions of white dwarf stars composed of carbon and oxygen, were instrumental as distance indicators in establishing the acceleration of the universe's expansion. However, the physics of the explosion are debated.

Laminar burning velocity blending laws using particle imaging velocimetry
Applications in Energy and Combustion Science, 2023 One of the most essential inherent characteristics of a combustible mixture is laminar burning velocity. Because of its relevance, many methods for measuring laminar flame velocity have been devised.

Laminar burning velocities of cyclopropane flames
Combustion and Flame, 2022 Cyclopropane, c-C3H6, the simplest cycloalkane, is seldom included in detailed kinetic mechanisms for hydrocarbons, though it may exhibit unusual kinetic features yet to be analysed due to a lack of studies of its combustion characteristics. In this work, laminar burning velocities of cyclopropane flames have been determined using the heat flux method ...

Propagation Properties of Turbulent Premixed Flames Neutral for Thermo-Diffusive Effects
International Journal of Automotive Engineering, 2020 Burning velocity is one of the important properties of premixed turbulent flames. Premixed turbulent flames are, in general, subjected to the thermo-diffusive effects in addition to the increase in the flame front area due to the influence of turbulence.
