Computational modeling of n-heptane droplet combustion in air–diluent environments under reduced-gravity

The combustion and extinguishment of n-heptane droplets in air–diluent environments under reduced-gravity are studied, where carbon dioxide, helium and xenon are used as diluents. A gasification model employing the volume of fluid (VOF) method was developed and implemented into the CFD package FLUENT. The droplet evaporation, combustion and parasitic current were validated by comparing with the previous study. The numerical results agree well...
