Upward flame spread along the vertical corner wall is a severe phenomenon due to its rapid spread rate in building fires. We conducted this study to investigate what kind of flow will be developed along the vertical corner wall by fires using a room corner model and placing a square gas burner on the floor. The parameter changed is the location of the burner respect to the walls. After a steady state condition was achieved, stream lines were visualized by particles illuminated by a laser sheet, and recorded by a 35mm camera. Results revealed that the oscillation of the flame, the long-range action of the turbulent plume and the swirl produced under some conditions are critical elements for understanding of turbulent entrainment and flame spread processes of the room corner fire.
