Turbulent Viscosity
Plz. I want help to find difference b/w Laminar viscosity and turbulent viscosity.What does it actually means.

Re: Turbulent Viscosity
Laminar viscosity is a property of the fluid. It is a macrosopic measure of how the fluid diffuses momentum due to motion at the molecular level. Turbulent viscosity is simply an analogy - in turbulent flow momentum is diffused or redistributed via the action of turbulent eddies, and this action is "analogized" to be like the action of momentum diffusion due to molecular motion. Hence the artifice of a turbulent or eddy viscosity is adopted.
