Abstract
The energetics and dynamics of n- heptane droplets evaporating in their own 800 K vapour at 1 and 10 bar have been studied using a finite-volume-based numerical method at intermediate Reynolds numbers. Droplet mass, Reynolds number, liquid heating rate, Nusselt number and drag coefficient histories have been obtained. The results show that liquid-phase heating plays an important role in overall droplet behaviour, particularly at elevated pressures. A simple liquid heating model is also presented which accounts for internal circulation through the use of an effective thermal conductivity. This enhanced diffusion model, together with a set of heat transfer and drag correlations, is shown to predict droplet behaviour in good agreement with the detailed numerical results.
