Abstract
In this study, combustion process is simulated for two-phase fuel flows (droplets of the liquid fuel and gas mixture of the fuel vapor and oxygen) using a combination of Lagrangian–Eulerian approaches. The Lagrangian is used to track for the liquid fuel droplets in the gas mixture region, while the Eulerian is used to gas mixture features accordingly. A two-way coupling is employed to take into account the interaction between gas mixture and liquid droplets. Evaporation process is followed D2-law with satisfaction of mass conservation. A reduced chemical kinetic model is employed instead of the detailed chemistry of fuel. The obtained numerical results are used to study and analyze the combustion process and physical insights. The effects of droplet size on the detonation characteristics are briefly discussed.
