Flame Behavior Of Bifurcated Jets In A V-Shaped Bluff-Body Burner, Hsiu Feng Yang, Ching Min Hsu, Rong Fung Huang

Journal of Marine Science and Technology

A plane fuel jet bifurcated into two streams of jets by a V-shaped bluff-body burner with co-flowing air streams was studied. The flame behavior, length, and temperature distributions of the bifurcated jets were experimentally examined. Flame behavior was characterized by flame visualization and instantaneous photograph. The flame length characteristics was obtained by using the long-exposure flame images. The temperatures distributions were measured by using a finewire thermocouple. Three characteristic flame modes were revealed—attached flame, transitional flame, and lifted flame. The flame length and width of the bifurcated jets increase with the increase of the Rec in fixed Rea. The length …
