要約

Computational fluid dynamics results of an evaporating suspended multi-component liquid fuel droplet are presented. The droplet consists of n-heptane, n-decane or a mixture of the two and it is held in suspension at the end of a thin diameter pipe. The droplet is exposed to a uniform air flow having temperature higher than that of the droplet. The Navier- Stokes equations are numerically solved together with the VOF methodology employed for tracking the liquid-gas interface using an adaptive local grid refinement methodology. The vapour concentration of each component within the air is calculated from its corresponding transport concentration equation. The droplet temperature and its evaporation rate are predicted as function of time using a local evaporation model applicable to cases where the droplet's shape deviates from the spherical one. The numerical results are compared against experimental data available in the literature. The 'final' equilibrium position of the suspended droplet is predicted as well as the internal liquid circulation which results to the entrapment of the more volatile species inside the droplet centre.
