Question on Anhedral and airflow

[kamrav]

I need some help if possible, please

With regard to trailing edge vortices and wake turbelence, textbooks all indicate airflow on the lower surface of the wing moving towards the wingtip, and airflow on the upper wing surface moving towards the root, thus forming a vortice. There is also the pressure differential to consider when looking at the whole effect. However, almost all the sketches show wings with dihedral.

There is always the possibility that it is just pure coincedence, but another pilot almost convinced me that when standing in front of a airplane with anhedral, the airflow on the upper and lower surfaces might be the opposite as to the abovementioned.


Any help will be appreciated. Thanks
