Beschreibungen/Notizen
Instantaneous spectral radiation intensities of three standard
turbulent jet flames were measured and simulated in this study. In the
simulation, a recently developed technique was adapted to reconstruct the local
integral time and length scales in the flames. The simulated radiation
properties, including mean, root mean square, probability density function,
power spectral density and autocorrelation coefficient, were generally within
10% of the measurements. The macro time and length scales were found to increase
with increasing distance from the axis and the radial averages of these scales
were found to increase with down stream distance but decrease with Reynolds
number.
