Web6 de sept. de 2024 · These equations are used when the fluid is in a turbulent flow. They look almost exactly like the Navier-Stokes equations, except for the last term. This is called Reynolds stress tensor. It is the quantity that allows us to account for the turbulence in the fluid. In the RANS equations, the quantities we use are averaged on a time interval.
