A fuel droplet vaporization model in a hot air stream

摘要

The gasification behavior of a fuel droplet has been studied. The convective heat transfer is focused on in most literature on droplet evaporation. In this paper, a mathematic model of droplet evaporation is improved. Considering the presence of simultaneous mass and heat transfer at the interface between phases, a proper heat transfer equation for droplet evaporation model is established. Based on the model, a computer simulation program was developed, and the predictions of the model are compared with the experimental data. Sample calculations show the capabilities of the model for droplet evaporation.
