Laser scattering measurements in turbulent diffusion flames
The application of a laser light scattering technique based on Mie scattering from small seeding particles has been investigated for flames. Because of the requirement for inertness of the particles in the flame, an investigation has been performed on the behavior of various types of refractory particles in a premixed hydrogen-air flame. In addition, attention has been given to the possible role of particle agglomeration by means of a Mie scattering computation. The technique was applied to a horizontal, turbulent, hydrogen diffusion flame issuing into a co-flowing air stream. The present measurements of mean fuel atom mass fractions were in good agreement with probe-sampled values and indicated that the latter measurements were between conventional and Favre averages. Probability density functions of the scalar indicated the bi-modal form typical of free shear layers.
