内容記述 | The present study aims to obtain a fundamental understanding of the mechanism of instabilities arising on a flame front propagating in a disk-shaped constant-volume chamber, by visualizing the flame front with Schlieren photography. The ignition was performed at the center or at a point on the periphery of the chamber to observe the effects of wall configuration. The mixtures selected were hydrogen-air, methane-air and propane-air with various equivalence ratios. As a result, it is found that the instabilities occur when the Lewis number of the unburned mixture is less than unity for the hydrogen-air and propane-air flames. This shows that instability is caused by the so-called "preferential diffusive instability". However, in the methane-air flame, for which the Lewis number is always near unity, an instability with very regular cells appears when the flame approaches the wall for any value of the equivalence ratio. This instability may be interpreted as a "hydrodynamic instability" affected by the presence of the wall. | |||||
