✦ Synopsis

Measurements are presented for a turbulent diffusion flame jet of carbon monoxide in coflowing air. Detailed profiles of average velocity, turbulence intensity, average temperature, and species concentrations were measured at a Reynolds number of 1.14 × 104. Several checks on the data indicated good accuracy of the measurements. A model was also developed for turbulent diffusion flames on the basis of their local laminar flame structure. Laminar flame calculations, using a global reaction rate for CO oxidation, provided unique relationships between thermochemical variables and the mixture fraction. These relationships along with a Ke-g model of turbulence in Favre-averaged form were used to make predictions in the CO/air diffusion flame jet. The model predictions showed good agreement for x/D < 50, with some discrepancy for x/D > 50.

This work considers the applicability of different versions of the k-e hypothesis of turbulence for flame modeling. Utilizing similarity solutions, we find that the k-e hypothesis gives a finite radius for a weak axysimmetric plume above the heat source. The radius of this plume is defined as an eig

Liftoff heights of turbulent diffusion flames have been modeled using the laminar diffusion flamelet concept of Peters and Williams [A/ AA J., 21:423-429 (1983)]. The strain rate of the smallest eddies is used as the stretch describing parameter, instead of the more common scalar dissipation rate. T
