2008). Friction forces are typically assumed to be strong for small drafts in convection, but cannot directly be measured, and could be small in some circumstances. The degree of mixing and ...

The particle size at which convective diffusion is effective depends on velocity and external force fields, but is usually in the submicron range. The intensity of the Brownian motion increases as ...

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Convection in a liquid Convection in a liquid can be seen ...
