Leading-Edge Velocities and Lifted Methane Jet Flame Stability

Figure 5

(a) and (b) Streamlines passing through the left (a) and right (b) flame edges of case 2 . (c) Velocity variation at the left flame edge of case 2 . The points’ velocities in the polygon are 0.42 m/s, 0.8 m/s, 0.56 m/s, 0.56 m/s, and 0.84 m/s (ordered by left to right and top down). The velocity of point 5-c2 is 1.7 m/s. (d) Velocity variation at the right flame edge of case 2 . The six points’ velocities in the rectangle are 0.65 m/s, 0.79 m/s, 0.49 m/s, 0.21 m/s, 0.2 m/s, and 0.07 m/s (ordered by left to right, top down). The velocities of points 5-d1 and 5-d2 are 1.4 m/s and 1.35 m/s.
