تعريف reynolds number في الإنجليزية الإنجليزية القاموس.

a dimensionless parameter that determines the behavior of viscous flow patterns. In pipe flow a value less than about 2,000 (known as the critical Reynolds number) produces laminar flow, one above about 3,000 produces turbulent flow (intermediate values produce unpredictable behavior)

In fluid mechanics, a number that indicates whether the flow of a fluid (liquid or gas) is absolutely steady (in streamlined, or laminar flow) or on the average steady with small, unsteady changes (in turbulent flow; see turbulence). The Reynolds number, abbreviated NRe or Re, has no dimensions (see dimensional analysis) and is defined as the size of the flow as, for example, the diameter of a tube (D) times the average speed of flow (v) times the mass density of the fluid () divided by its absolute viscosity (). Osborne Reynolds demonstrated in 1883 that the change from laminar to turbulent flow in a pipe occurs when the value of the Reynolds number exceeds 2,100
