# Turbulence Modelling - Engineering - Fluid Mechanics

Turbulence modelling - The Reynolds equations are part of the Navier-Stokes equations for turbulent flows. These equations are useful in the predictions of time-averaged (mean) quantities when the flow is turbulent

# Introduction to Turbulence - Engineering - Fluid Mechanics

A simple introduction of turbulence - There are no precise definitions of turbulence. This is similar to diseases in a sense that the diseases can only be diagnosed by their symptoms.

Then, how do we know that a flow is turbulent?

We...
