Effect of Aerosol Flow Parameters on the Flame Blow-Off Velocity and Flame Stability Limits in a Channel with Sudden Expansion

The flame stabilization mechanism was implemented in the flow of pseudoliquid fuel through an axisymmetric channel with sudden expansion. Relationships between the flame blow-off velocity and flame stabilization limits were established based on the channel geometric parameters and initial characteristics of the flow of aluminum aerosol particles. Dependencies of flame blow-off velocity in the flow of aluminum aerosol particles ASD-1 and ASD-4 over a wide range of air-fuel ratio variations were obtained.
