Explore: Reynolds Averaging

The Reynolds-averaged Navier–Stokes equations (RANS equations) are time-averaged equations of motion for fluid flow. The idea behind the equations is Reynolds

Reynolds averaging of turbulent flows, where quantities such as velocity are expressed as the sum of mean and fluctuating components. Such averaging allows

In fluid dynamics, the Reynolds stress is the component of the total stress tensor in a fluid obtained from the averaging operation over the Navier–Stokes

Favre averaging is the density-weighted averaging method, used in variable density or compressible turbulent flows, in place of the Reynolds averaging. The

components. Such averaging allows for 'bulk' description of turbulent flow, for example using the Reynolds-averaged Navier–Stokes equations. Reynolds' contributions

Burton Leon Reynolds Jr. (February 11, 1936 – September 6, 2018) was an American actor most famous during the 1970s and '80s. He became well known in television

a Reynolds operator is a mathematical operator given by averaging something over a group action, satisfying a set of properties called Reynolds rules

This is sometimes referred to as URANS. There is nothing inherent in Reynolds averaging to preclude this, but the turbulence models used to close the equations

theory, a Reynolds decomposition is a mathematical technique used to separate a field into its mean and fluctuating components. A Reynolds decomposition

by measured root-mean-square (RMS) velocity fluctuations. In the Reynolds-averaged Navier Stokes equations, the turbulence kinetic energy can be calculated
