Sooting Yale Coflow Diffusion Flames


Standard Constant-Mass Doped Flames

For details on the flame conditions, thermal boundary conditions, flowrates and mole fractions, and burner dimensions, click here.

Soot temperatures and volume fractions are based on color ratio pyrometry using a Nikon D90 camera. Data was published in Ref. **. Here, soot optical properties were assumed to be constant throughout the flame with the emissivity varying with wavelength to the -1.38 power.

The data is in a tab delimited, formatted text file, consisting of a two-dimensional array of floating point values. The data array size is 1668 x 383. The matrix represents an image with pixel spacing of 0.035 mm (28.412 pixels/mm). The first element of the matrix corresponds to the value in the upper left corner of the images shown. This type of data can be read in directly to Matlab using the load command, or to Python using the numpy.loadtxt command.
