Circulation around vortex core

Postby ridhwan » Tue Jan 19, 2010 4:49 am

Hello, I'm new in Tecplot. Is there a tool in tecplot 360 to calculate circulation around the vortex core?

Or to calculate closed integration of $oint \vec{u} \cdot \vec{dl}$.

Hello Ridwan,

Are you asking whether Tecplot can display a vortex core, or are you just asking if Tecplot can perform a calculation on a vortex core that has already been displayed?

Thank you Jim for the macro.

I'll look forward to test the macro soon. At the moment, my circulation calculation works very fine using the Vector Dotted with Unit Tangential as suggested by Dave.

Many thanks for your help.

Yes can anyone elaborate on how to create a new circular (closed path) zone onto which the data can be interpolated?

[EDIT] I suppose for circulation you can just calculate the vorticity and create a solid circular zone over which one integrates...but I don't know how to get the "line" zone i.e. hollow circular zone

Hi Tecplot users!
I've already used the Analyser function to extract vortex centre lines.now i want to display vortex core radius..is there any developed utility in tecplot for this purpose.
i would appreciate your help.
