On Stabilization and Blowoff of Inverted Spherical Flames

A one-dimensional model for a sink-stabilized spherical flame is proposed and analyzed. It is shown that the stabilization occurs only within a certain range of the sink flow rates, beyond which the flame sulfers either blowoff or flashback. It is suggested that the system may be helpful for underst...

Description
Summary:A one-dimensional model for a sink-stabilized spherical flame is proposed and analyzed. It is shown that the stabilization occurs only within a certain range of the sink flow rates, beyond which the flame sulfers either blowoff or flashback. It is suggested that the system may be helpful for understanding the flame stabilization in the flow wake past a blulf body, the principal motivation for the present study.
