Experimental Study on the Influence of Different Coal Species on Gas and Coal Dust Explosion
To further explore the propagation law of gas coal dust explosion with different coal species involved, 3 kinds of representative coal dust were tested in a self-made semi-enclosed pipe, and the flame propagation speed, flame surface luminescence ...

Measurement of turbulent flame speed of natural gas/air mixtures at elevated pressure [PDF]
Turbulent flame speeds were measured over a range of pressures to 0.8 MPa using a jet flow apparatus fired with a synthetic mixture representing a mid-European natural gas. The equivalence ratio empty set was 0.9.

Flame advection and propagation algorithms [PDF]
We present a simple algorithm for approximating the motion of a thin flame front of arbitrary shape and variable connectivity, which is advected by a fluid and which moves with respect to the fluid in the direction of its own normal. As an application, we examine the wrinkling of a flame front by a periodic array of vortex structures.

Curvature and confinement effects for flame speed measurements in laminar spherical and cylindrical flames. [PDF]
This paper discusses methods used to obtain laminar flame speeds in spherical laminar premixed flames. Most recent studies express the laminar flame consumption speed as ρb/ρudR/dt, where R is the flame radius and ρb/ρu is the ratio of the burnt to the ...
