Abstract

The combustion of sodium droplet is simulated numerically. The flow fields in and around the droplet are obtained by solving the Navier-Stokes equations and the energy conservation equations. The reaction rate for the pre-ignition stage combustion is modeled using a kinetics based model, while that for the vapor phase after ignition is based on the mass transfer rate of oxygen. The droplet motion with temperature variation is shown, and compared with the existing experimental data, Reasonable agreement is shown between the simulated and the experimental results.
