Flames with sign-alternate speed in methane-air and methane-air-coal suspension mixtures in a vertical closed pipe
A. V. Pinaev, P. A. Pinaev Lavrentyev Institute of Hydrodynamics of Siberian Branch of the Russian Academy of Sciences, Novosibirsk, Russia
Abstract:
This paper presents the results of an experimental study of flames propagating with a sign-variable speed, in methane-air and coal-methane-air mixtures in a vertically located closed pipe at coal dust concentrations of 0.10 $\div$ 0.42 kg/m$^3$. The results of the study can be useful for developing combustion models and assessing dynamic and thermal effects during combustion of methane-air suspended coal in coal mines.
Keywords:
methane-air mixture, coal gas suspension, combustion wave, sign-variable flame speed, optical imaging of flame, flame speed pulsations.
