“…A single-pulse spontaneous Raman scattering apparatus, based on a flashlamp pumped dye laser (2-4 J pulse energy, k 4 8 8 nm), was used for point-wise measurements of the major species concentrations and the temperatures [1,2]. The spatial resolution was 0.6 mm (in x, y, and z direction), the temporal resolution 2-3 ps.…”

This SAND report documents the proceedings of the International Workshop on Measurement and Computation of Turbulent Nonpremixed Flames, held in Naples, Italy on July 26-27, 1996. Contents include materials that were distributed to participants at the beginning of the workshop, as well as a Summary of Workshop Accomplishments that was generated at the close to this Naples meeting.The Naples workshop involved sixty-one people from eleven countries. The primary objectives were: i) to select a set of well-documented and relatively simple flames that would be appropriate for collaborative comparisons of model predictions; and ii) to specify common submodels to be used in these predictions, such that models for the coupling of turbulence and chemistry might be isolated and better understood.These proceedings are also "published" on the Web and those interested in the ongoing process of data selection and model comparison should consult the workshop page for the most recent and complete information on these collaborative research efforts.

In order to model the conditional diffusive heat and mass fluxes in the joint probability density function (PDF) transport equation of the thermochemical variables, the diffusive fluxes are decomposed into their Favre mean and fluctuation. While the mean flux appears to be closed, the contributions of fluctuating fluxes are modeled with the interaction by exchange with the mean (IEM) model. Usually, the contribution of the Favre averaged diffusive fluxes is neglected at high Reynolds numbers. Here, however, this term is included to account for molecular mixing in regions, where turbulent mixing is negligible. This model approach is applied in steady state Reynolds Averaged Navier-Stokes (RANS)/ transported PDF calculations to simulate the heat transfer of wall bounded flows as well as the stabilization of a hydrogenair flame at the burner tip. For both flow problems it is demonstrated that molecular transport is recovered in regions where turbulent mixing vanishes.
