Diffusion mixing

Japanese: 拡散混合 - かくさんこんごう
Diffusion mixing

…The process of mixing in an actual mixer appears complex at first glance, but it can be considered a complex repeated process of simple convective mixing. In particular, when the mixing action is carried out continuously by the fine irregular motion of many individual components, it is considered a statistical mixing process and is called diffusive mixing (Figure 2). Examples of this include mixing by thermal motion of gas molecules, turbulent motion of fluids, and irregular vibration motion of solid powder particles. …

*Some of the terminology explanations that refer to "diffusive mixing" are listed below.
