Cambridge-Sandia Swirl Burner
The Cambridge-Sandia Swirl burner (SwB) was used in a number of experiments on combustion in stratified flows. A full description of the experimental set up can be found in the relevant papers.
Geometry
The burner consists of three concentric tubes, the inner one capped by a ceramic bluff-body. The inner and outer channels are fed by separate flow meters with given equivalence ratios.The outer mixture can be split between a tangential or axial inlet, leading to variable swirl. An outer, low velocity flow surrounds the burner.
