haha yes, I have not been to college in a looong time but I loved it, I am thinking of going back and maybe getting a masters because I miss learning.

thank you so much for the replies guys, it's all really appreciated, I feel like I'm back in college 🤩

is the effect similar if it was negative surface roughness? like if you had a dimple/dent/chip in a wing what would happen to the boundary layer, would it be similar to the golf ball example? because a wing is obviously not spinning, so can't see how that effect would also work on wings. would...

I was thinking more of insect buildup on airplane wings, surely the buildup, even if randomly distributed would have an effect, no, was thinking that it could possibly trigger an earlier transition. If I understand it correctly from what you said, the disturbances to the surface could trigger...

I was reading an article and it mentioned that surface roughness can affect boundary layer transition? How? I am just a casual reader of aerodynamics but have a background in engineering can anyone explain the physics behind surface roughness affecting boundary layers and flow separation? and...
