Secondary flow

Hi
I was wondering how we can quantify secondary flow in cfx post?

Thanks

There are plenty of approaches to evaluate secondary flow in the literature. What exactly about the secondary flow do you want to evaluate?

Hi Ghorrocks
I am working on bifurcation artery. I changed the curvature of the parent artery and I want to see how the curvature of the artery can change the hemodynamic parameter like wall shear stress. I 'm not really sure how to quantify the formation of the secondary flow at different curvature.??

Thanks

If you are interested in wall shear stress then look at that, CFX has that data in the results. But until you define exactly what it is about the secondary flows you are interested in we cannot help you.
