Turbulent Pipe Flow (LES)

Most fluid flows (gas or liquid) are turbulent in nature.These flows are characterized by unsteady and irregular fluctuations of transport quantities such as mass, momentum and species in both space and time. These fluctuations enhance flow mixing. Examples of these flows are widespread — from ocean waves and cyclones to airflow over an automobile, from jet engine exhaust to flow inside gas pipelines. Generally, there are two types of turbulent flow structures (or eddies) — large and small scale. Turbulence modeling attempts to capture these eddies to understand the overall flow field.

This SimCafe Fluids Course was developed by Dr. Rajesh Bhaskaran, Swanson Director of Engineering Simulation at Cornell University in partnership with Ansys, and was last modified by Sebastien Lachance-Barrett. It serves as an e-learning resource to integrate industry-standard simulation tools into courses and provides a resource for supplementary learning outside the classroom. In this tutorial, we will learn to model turbulent flow inside a pipe using the Large Eddy Simulation (LES) by following the end-to-end workflow in Ansys Workbench.
