Abstract

Transient heating and vaporization of cool dense spherical droplet-clouds are studied at supercritical conditions. High-pressure effects are considered for the outer homogeneous and inner heterogeneous flows of the cloud. Numerical results obtained from the present study reveal that droplets in such clouds are less likely to reach the critical mixing state than an isolated single droplet at equivalent supercritical conditions. Heat transfer from the hot surroundings is also less influential at supercritical conditions, resulting in relatively invariant-sized droplet-clouds. For such dense droplet clouds, the D2-law is invalid at both subcritical and supercritical conditions.
