Annular turbulent premixed flames have been stabilized by means of an 'opposed jet burner'. Determinations of the mean gas flow velocity, the intensity of turbulence, the Eulerian scale and the microscale have been made in the flame stabilization region; the thicknees of the flame has been estimated
Turbulent burning velocity St is determined for six premixed V-shaped turbulent flames. In addition to defining St with respect to the conventional flame surface, a definition based on an effective flame orientation is proposed. The results based on the flame surface increase significantly with dist
