TY - JOUR TI - Numerical simulation of sudden-expansion particle-laden flows using the Eulerian lagrangian approach AU - Mergheni Mohamed Ali AU - Sautet Jean-Charles AU - Ben Ticha Hmaied AU - Ben Nasrallah Sassi JN - Thermal Science PY - 2012 VL - 16 IS - 4 SP - 1005 EP - 1012 PT - Article AB - A Lagrangian-Eulerian model for the dispersion of solid particles in sudden-expansion flows is reported and validated. The fluid was calculated based on the Eulerian approach by solving the Navier-Stokes equations. A Lagrangian model is also applied, using a Runge-Kutta method to obtain the particle trajectories. The effect of fluid turbulence upon particle dispersion is taken into consideration through a statistical model. The predicted axial mean velocity and turbulent kinetic energy of both phases agree well with experimental data reported by Sommerfield.
