Understanding Laminar and Turbulent Flow

There are two main types of fluid flow - laminar flow, in which the fluid flows smoothly in layers, and turbulent flow, which is characterized by chaotic motion and large amounts of mixing. In this video, Efficient Engineer Channel explores the differences between these two flow regimes. It covers how Reynolds number can be used to predict which flow regime will occur for a specific set of flow conditions. And it will look at laminar and turbulent flows in pipes, and how the flow regime affects the pressure drop in a pipe. It willl also investigate why it is so difficult to simulate turbulent flow, and look at some of the different Computational Fluid Dynamics methods which can be used to simulate it.
