Diffuuttinen
Diffuuttinen is a term used in Finnish to describe phenomena or processes governed primarily by diffusion—the net movement of particles from regions of high concentration to regions of lower concentration as a result of random thermal motion. In this sense, a system is considered diffuuttinen when diffusion is the dominant transport mechanism, rather than advection or bulk flow.
Fundamental principles governing diffuuttinen processes include Fick's laws. Fick's first law states that the diffusion flux
Applications and examples span multiple fields. Diffusion occurs in gases (gas diffusion and mixing), liquids (solute
Measurement and modeling typically involve determining D through tracer experiments or diffusion cells, and using numerical
