This study investigates the flame transition velocities at various intercylinder separation distances for side-by-side dual blowing cylindrical burners. The flame transition velocity is defined as the airflow velocity at which the envelope flames over the two burners transform into two separate wake flames. The transition velocity increases as L decreases through the range of 1.2D ≦ L ≦ 2.5D (D is diameter of cylindrical burner). When L > 2.5D, the transition velocity remains constant because the two flames do not interact with each other.
