Abstract

In the present investigation we have experimentally determined the limiting values of the plate temperature and chamber pressure below which droplet ignition by the hot plate cannot be achieved. The results show that ignition is strongly influenced by the basic Leidenfrost droplet vaporization behavior, which is non-monotonic with respect to the plate temperature. The main limitation of the present study is that the sizes of the droplets are substantially larger than those in realistic fuel sprays. Thus, the results reported herein should be viewed as being qualitative instead of quantitative. Further experiments involving smaller droplets are desirable.
