Flame Propagation in a Nonuniform Mixture: Analysis of a Propagating Triple-Flame [PDF]

open access: yesCombustion Science and Technology, 1991
Abstract A situation in which a dilffusion flame reaches an end at some position in a medium of non-premixed reactants is studied. The mixing of reactants that takes place ahead of the diffusion flame leads to the formation of a “triple-flame”, a structure which consists of a fuel-rich premixed flame, a fuel-lean premixed flame, and a diffusion flame ...

Generation of adverse pressure gradient in the circumferential flashback of a premixed flame [PDF]

open access: yes, 2016
Circumferential upstream propagation of a premixed flame in a region confined between two concentric tubes is considered. The cold flow in this configuration features rotational motion and the flame is modelled as an interface separating the burned and ...

Experimental Study on the Influence of Different Coal Species on Gas and Coal Dust Explosion

open access: yesMeikuang Anquan, 2020
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 ...

Experimental and theoretical investigation of the flashback of a swirling, bluff-body stabilised, premixed flame [PDF]

open access: yes, 2015
Flashback of an open turbulent, premixed flame in a swirl burner with central bluff-body is considered. The aim is to obtain further understanding of the physical mechanisms responsible for the upstream flame propagation.

Rotational effects in thermonuclear Type I Bursts: equatorial crossing and directionality of flame spreading [PDF]

open access: yes, 2015
In a previous study on thermonuclear (type I) nursts on accreting neutron stars we addressed and demonstrated the importance of the effects of rotation, through the Coriolis force, on the propagation of the burning flame.

Original scale simulation of gas explosion at heading face in coal mines

open access: yesMeikuang Anquan, 2023
To study the propagation of gas explosion shock wave and flame in coal mine heading face at real scale, the numerical simulation software of gas explosion was used to establish roadway models of different scales, and the influence of premixed gas ...
