I honestly didn’t expect this quality of analysis on the topic. I believe that another phenomenon is required to complete the explanation in addition to Newton. Couette flow explains why streamlines closest to the wing tend to follow the shape of the wing. Hence the vectoring effect. I’m sure a better article exists but Wikipedia is a bit lacking unfortunately. [1]Couette Flow - https://en.m.wikipedia.org/wiki/Couette_flow https://en.m.wikipedia.org/wiki/Couette_flow
