One of the most common strategies to model a turbulent fluid flow is to attempt to model the average, or mean flow field, by expanding the velocity field into an average and a fluctuating component. This video introduces this idea of “Reynolds averaging“ and shows how to obtain a mass continuity equation for the mean flow.
