- Abstract
- Many studies have been performed to quantify the vaporization process for both single droplets and multiple-droplet arrays impacting on hot surfaces. For the studies found in the published literature, the full span of the droplet vaporization processes is usually reported. These would include evaporation, nucleate boiling, film boiling, and Leidenfrost transition. The present investigation is limited in the span of vaporization processes studied, being only concerned with the evaporation of a droplet on a hot surface. The study does report very detailed results for spatial and temporal variation of the heat flux at the exposed surface of the droplet, and for temporal variation of the droplet volume. Limiting the study to evaporation implies that conditions are maintained under which nucleate boiling is fully suppressed.
