How can I calculate Swirl number at different heights in a column

mali28 · October 11, 2011, 12:10

I have a cylindrical column with swirling flow. I want to calculate swirl number at different positions along the height of the column. How can I calculate it using Fluent12.1 can any one help please?

Thank you.

I think the swirl nr is not a default value in Fluent. So first go to Define/Custom Field Functions

Than, you should creat planes and in the Report menu, you can check at each plane.
