Laminar Pipe Flow

Created using ANSYS 13.0. Tutorial instructions work with ANSYS 14.0 and 15.0. There are minor layout changes in ANSYS 15.0. 

Note

This tutorial has videos. If you are in a computer lab, make sure to have head phones.

Info

This module is from our free online simulations course at edX.org (sign up here). The edX interface provides a better user experience, so we recommend going through the module there.

1. Introduction

What is Computational Fluid Dynamics or CFD?

What's Under the CFD Blackbox?

Commercial CFD software such as ANSYS Fluent is a blackbox for the CFD user. It is important for the user to know the major elements of what's under the blackbox in order to use the tool effectively and avoid "garbage in, garbage out". Earlier, we discussed a framework that lays out the major elements of what's under the blackbox and used that in the FEA case studies. Please review that section since we'll be using that framework for the CFD case studies also.

Go to Step 2. Finite Volume Method

Go to all (FLUENT)

Solve this problem numerically using ANSYS FLUENT. Present the following results:

  • Velocity vectors 

  • Velocity magnitude contours 

  • Pressure contours 

  • Velocity profile at the outlet

  • Skin friction coefficient along the wall

Provide comparisons of the results with the full-developed analytical solution. Verify your results.
