Abstract
Blowout experiments of a methane-air diffusion flame have been performed by using water vapor. The water vapor is produced due to the impact of a water droplet onto a heated wall. The water droplet diameter is varied from 3.4 mm to 10.4 mm and the temperature of the heated plate, from 100℃ to 430℃. The formation probability of the water vapor vortex ring and the blowout probability were measured. From the experimental results, the maps of the formation condition of the water vapor vortex ring and the blowout condition are made.
