abstract

Large Eddy Simulation (LES) of turbulent spray combustion flow was conducted. An experimental model of the spray combustor which has benchmark experimental database is chosen to validate the present numerical simulation. The governing equations for the gas phases are discretized in curvilinear boundary-fitted coordinate system, and the fuel droplet motion equations are described in Lagrangian representation. The numerical results such as gas-phase mean velocities agree with the experimental results. Three dimensional vortical structures and droplet motion by swirling air are well visualized, and droplet velocities agree with experimental results.
