Reynolds number

English Etymology en British engineer Osborne Reynolds = 1. Noun en physics A dimensionless parameter that determines the behavior of viscous flow patterns. In pipe flow a value less than roughly 2,000 (known as the critical Reynolds number) produces laminar flow, one above about 3,000 produces turbulent flow (intermediate values produce unpredictable behavior). en 1995 Flow Noise Modeling, Measurement, and Control William Lawrence Keith 45 One certainly can argue that not all low-speed streaks lead to liftup, although if the local Reynolds number exceeds the transition limit, it is certain that eventual transition will occur to the hairpin vortex liftup, which ultimately leads to the breakup state. en 1995 Kalra Publications Pvt.
