Effects of environmental flow velocity on the evaporation of free droplets Jeong, Seong-Sik; Ha, Jong-Ryul; Lee, Jung-Sun; Lee, Sang-Seok; Kawaguchi, O;
An experimental study has been performed to obtain the effect of relative velocity between droplet and environmental gas on the evaporation of a n-heptane free droplet of 180 m in diameter flying in a hot and normal pressure air flow. Measurement of droplet diameter and velocity was conducted in a series of time by an electrically controlled optical system. From the experimental results, an empirical equation associated with the relation between evaporation rate constant and relative velocity was obtained.
