Simplified Governing Equations

In the paper “Instability of Taylor-Couette Flow between Concentric Rotating Cylinder” by Hua-Shu Dou, Boo Cheong Khoo, and Khoon Seng Yeo the equation for the critical condition of primary instability is simplified for a concentric rotating cylinder. It is given and solved in the equations below. In order to incite Taylor-Couette flow, must be between 370-389 so a value of 380 was chosen as for the calculation.


A few words on the formatting in the following instructions:

  1. Notes that require you to perform an action are colored in blue

  2. General information is colored in black, but does not require any action

  3. Words that are bolded are labels for items found in ANSYS AIM

  4. Most important notes are colored in red

We are ready begin simulating in ANSYS AIM. Open ANSYS AIM by going to Start > All Apps > ANSYS 18.1 > ANSYS AIM 18.1. Once you are at the starting page of AIM, select the Fluid Flow template as shown below.
You will be prompted by the Fluid Flow template to either Define new geometry, Import geometry file, or Connect to active CAD session. Select Define new geometry and press Next. Finally, check the Swirling flow box in the Additional flow physics and press Finish.

Go to Step 2: Geometry
