Coefficient of mutual diffusion

From Glossary of Meteorology



coefficient of mutual diffusion

A quantity in the kinetic theory of gases that measures the tendency of gases to diffuse into one another in nonturbulent flow.

This diffusion coefficient is a property of the gases in question and of the assumed nature of the molecular impacts in the diffusion process.
