Gravity wave — In fluid dynamics, gravity waves are waves generated in a fluid medium or at the interface between two media (e.g. the atmosphere or ocean) which has the restoring force of gravity or buoyancy.When a fluid parcel is displaced on an interface or… … Wikipedia
Reynolds stresses — In fluid dynamics, the Reynolds stresses (or, the Reynolds stress tensor) is the stress tensor in a fluid due to the random turbulent fluctuations in fluid momentum. The stress is obtained from an average (typically in some loosely defined… … Wikipedia
Reynolds-averaged Navier–Stokes equations — The Reynolds averaged Navier–Stokes (RANS) equations are time averaged [The true time average ( ar{X} ) of a variable ( x ) is defined by: ar{X} = lim {T o infty}frac{1}{T}int {t 0}^{t 0+T} x, dt. For this to be a well defined term, the limit ( … Wikipedia
