An Experimental Investigation of Ignition and Flame Stabilization in a Turbulent Mixing Zone


Becker, Jack Lincoln (1952) An Experimental Investigation of Ignition and Flame Stabilization in a Turbulent Mixing Zone. Engineer's thesis, California Institute of Technology. doi:10.7907/BFQK-V510.


The present investigation constituted the first part of an attempt to isolate the essentials of flame stabilization behind a bluff body. It is thought by many that such a flame is initiated and stabilized by heat transfer, the diffusion of active chemical species, and the chemistry of the combustible mixture involved. The ignition of a fresh combustible mixture by a hot stream of gas provides possibility for detailed study of flame stabilization because of heat transfer. Results indicate that the method followed herein to produce ignition resulted in the formation of two distinct types of flames. One flame seemed to be affected primarily by temperature, the other was affected by temperature, stream velocity and fuel-air ratio. The work was carried on as part of a study of flame stabilization being conducted at the Jet Propulsion Laboratory, California Institute of Technology, Pasadena, California.
