Hi,

I am a CFX-User. I want to post the swirling number for a rotational Flow.

The most known definition of the swirling number S is a relation of the

S = dotD/(dotI * r)

Thanks for your help

What is D and I? What does dot D mean?

I calculated the swirl and tumble numbers for an IC engine in-cylinder flow using the volumeInt() functions. I assume you can do the same.
