"In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime. The moving fluid creates a space devoid of downstream-flowing fluid on the downstream side of the object. Fluid behind the obstacle flows into the void creating a swirl of fluid on each edge of the obstacle, followed by a short reverse flow of fluid behind the obstacle flowing upstream, toward the back of the obstacle. This phenomenon is naturally observed behi… " - Eddy cfd

The first turbulence models accounted for turbulence effects through a concept termed the “eddy viscosity”. Essentially, the eddy viscosity (or turbulent viscosity) reflects an apparent increase in viscosity caused by small-scale chaotic motions in a fluid.

WebThe eddy viscosity ratio is especially convenient to use in low-turbulence cases where it is difficult to guess any characteristic turbulent length scale. Typical examples are external aerodynamics, like flow around cars, aircrafts and submarines. For internal flows and flows where the origin of the turbulence can be related to some physical ...
