User:AlyssaML/Eddy diffusion
My chosen topic of study is eddy diffusion in the environment.
The size of eddies decreases as kinetic energy is lost, until it reaches a small enough size for viscosity to control, resulting in kinetic energy dissipating into heat.[1] The concept of turbulence or turbulent flow causes eddy diffusion to occur. [2] The theory eddy diffusion was developed by Sir Geoffrey Ingram Taylor. [3]The concept of turbulence or turbulent flow causes eddy diffusion to occur. [4] The theory eddy diffusion was developed by Sir Geoffrey Ingram Taylor. [5]The eddy diffusion coefficient is used in the diffusion equation, to describe the dispersion or mixing of solutes in fluid or atmospheric systems. [6] In natural systems, the vertical component of eddy diffusion, is an important parameter for modeling and describing atmospheric variations due to turbulence and convection.[7]This process of eddy diffusion is the foundation for the structure of the atmospheric boundary layer.[7] In rivers, the size of the eddies cause fluctuations in the river's velocity. [8]The size of eddies in rivers are usually limited by the depth of the river, due to a rivers depth is usually much smaller than it's width.[8]
