- Abstract
- The Eulerian-Lagrangian approach has been applied to numerically analyze the characteristics of the turbulent particle-laden, swirling flow in a coaxial-jet combustor. Turbulence is represented by the k-ε model and the particle dispersion by turbulence is modeled by the stochastic tracking approach. A mixture of air and lightly loaded, spherical, glass-particles with a prescribed sizedistribution enters the primary jet, while a swirling stream of air flows through the annulus. Special emphasis is given on the particle dispersion characteristics such as the particle trajectories, residence times, and size distribution. Numerical results are compared with experimental data in terms of mean and turbulent quantities for carrier and discrete phases. Numerical results indicate that the present approach yields the reasonably good conformity with experimental data.
