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 equations to account for turbulent fluctuations in fluid momentum. == Definition == The velocity field of a flow can be split into a mean part and a fluctuating part using Reynolds decomposition.
