“…Thus, measurement of the spatial variations through a stabilized laminar flame replaces the necessity of time resolved measurements of transient particles combustion. It is worth noticing that many researchers have considered the one-dimensional simulation of flame propagation through particles cloud [28,[31][32][33][34][35][36] and the steady-state condition [11][12][13]28,[32][33][34]. According to the aforementioned points, a onedimensional and steady state model is considered in the present research.…”

“…Theoretical work has also been done on the explosion of dusts, including coal dust in air and in long tubes based on one-dimensional model (Chi & Perlee, 1974;Clark & Smoot, 1985;Pickles, 1982). However, the reason for a tube wall causing a flame to accelerate and induce a shock wave has not been described clearly in one-dimensional treatments.…”

Abstract.A new pneumatic dispersion system for obtaining a good quality uniform dust suspension in a horizontal dust combustion tube was developed. The effect of three different dispersion techniques on self-sustained dust flame acceleration in such a combustion tube was examined. The importance of the dispersion quality in the test tube for maintaining a self-sustained dust flame acceleration was demonstrated. A combustion tube for studies of flame acceleration in fine aluminum dust-air mixture and its transition to detonation under industrial ignition conditions was constructed in the course of the present study. It consists mainly of an initiation section and a test section. The initiation section must be equipped in a well-developed dispersion system for creating a good dispersion condition in the test tube. The length of this section is 3 meters. The test tube requires only to distribute uniformly the dust over the bottom of the tube prior to the experiment. The aluminum dust spherical in shape with 6 #m in diameter was used for tests. Experimental results demonstrated that the increase in flame velocity is roughly linear through the entire length of the test tube. The highest flame propagation velocity in fine aluminum dust-air mixture approaches some 1200m/s at a distance of 4.8m from the ignition plate.
