Reynolds number

English

Etymology

Named after British engineer Osborne Reynolds.

Noun

Reynolds number (plural Reynolds numbers)

1. (physics) 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).

Translations
