Vortex in Cell Method
 

Hi, Dears

I have a question about stretchting term.

I am Calculating 3D flow of Rectangular Wing with angle of attack by Vortex in cell method.I will try to analyze tip-vortex.

Now I don't involved stretching term at Re=100.

When calculating 3D wing with angle of attack at Low Reynolds number, Is stretching term important?

I want to know that stretching term effect wing flow at Low Reynolds number.

Thank you for readig this article.

Why aren't you including the term in the calculation, since it doesn't require significantly more cost? Stretch may or may not be important, depending on the problem at hand: the objective of your solution would be to analyze that (I'd assume)

The strectching term is indeed very important in such a 3D rollup process. It will be important in the outer core of the tip vortex and can play a predominant role in the turbulence presence/absence in the core.
