n: the erratic, nonlinear flow of a fluid, caused by high velocity. Characterized by random eddying flow patterns superimposed on the general flow progressing in a given direction.

n: A type of fluid flow characterized by swirling or chaotic motion as the fluid moves along the flow path. This is a preferred flow regime for mud removal during primary cementing because it is perceived to result in better removal of mud, especially of mud

non laminar flow, usually above a Reynolds number of about 3000. The Blasius equation estimates the friction factor for NRe values less than 100,000 as fB = 0.0791 / NRe0.25.
