Experimental Study on Local Flame Properties of Hydrogen Added Hydrocarbon Premixed Turbulent Flames
This experimental study is performed to investigate directly the local flame properties of turbulent propagating flames at the same weak turbulence condition (u'/SL0=1.4), in order to clarify basically the influence of the addition of hydrogen to ...

Flow divergence in the turbulent premixed flames
In order to elucidate the flow divergence in the rich propane-air turbulent premixed flames, the flow fields of lean and rich propane-air and methane-air turbulent premixed flames of the identical conditions of laminar burning velocity and characteristic

Type Ia Supernova Explosion Models: Homogeneity versus Diversity [PDF]
Type Ia supernovae (SN Ia) are generally believed to be the result of the thermonuclear disruption of Chandrasekhar-mass carbon-oxygen white dwarfs, mainly because such thermonuclear explosions can account for the right amount of Ni-56, which is needed ...

On defining the turbulent burning velocity in premixed V-shaped turbulent flames [PDF]
Abstract Turbulent buring velocity S t is determined for six premixed V-shaped turbulent flames. In addition to defining S t with respect to the conventional flame surface, a definition based on an effective flame orientation is proposed. The results based on the flame surface increase significantly with distance from the flame stabilizer ...

Small-scale Interaction of Turbulence with Thermonuclear Flames in Type Ia Supernovae [PDF]
Microscopic turbulence-flame interactions of thermonuclear fusion flames occuring in Type Ia Supernovae were studied by means of incompressible direct numerical simulations with a highly simplified flame description.
