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.
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.

Scalar data: The data is provided in simple text format, as described in the tables below. Zip files contain the dataset for all operating conditions.
Velocity data - LDA: All mean and RMS for the LDA results are given as reduced moments of velocities in the two directions as text files. Z is the axial position, with velocity components U, V and W for the radial, axial and tangential velocities, respectively.

Velocity data - 2D PIV: All mean and RMS for the PIV results are given as reduced moments of velocities in the two directions as text files.
