Experimental investigation of the flow field during combustion in narrow circular ducts
… quartz tubes yielded cycles of ignition, flame propagation, and extinction. This phenomenon was studied with the intent of determining the flow structure that underlay the observed oscillatory motion. The fluid motion during the oscillations was visualized by seeding TiO2 micron-sized …

Experimental investigation of flame propagation in long, narrow tubes
Combustion of premixed propane-air flames propagating in horizontal quartz tubes of small diameter (6.4 mm) was studied using high-speed photography and Particle Streak Velocimetry (PSV). Several regions of propagation were established, including an initial region of uniform propagation, a …
