o molecular characteristics, mildly increasing with Prandtl number (Pr) and decreasing with diffusivity ratio (? ). Theory is successfully tested by a series of direct numerical simulations which span a wide range of Pr and? . Double diffusion occurs on the micro-scale and computer technology is just now reaching the processing speeds needed to fully resolve this complex phenomenon in three dimensions. In addition to the well-known ?salt fingering? within the oceans, double diffusion occurs in many other statically stable regions, both terrestrially and beyond our atmosphere. Understanding this phenomenon could prove essential as we continue to discover new worlds and new areas within our galaxy, including here on terra firma.
