Im posting this to help me learn: Boundary layer- The area between the flow in contact with the object (here no slip is applied so u = 0 at surface) and the flow that is not affected by the viscous forces of the Object (free stream velocity). Thanks for great explanation!
Indeed Luke! Keep in mind that that definition is useful for a flat plate, but more difficult for the flow around a 3D object (where most of the flow is actually "disturbed", also outside of the boundary layer).
The last point on induced turbulence to move the separation location is very interesting. Down a rabbit hole of athlete tape I go… Thanks for posting these videos, complex topics fantastically explained
Is the reasoning behind dimples about the increase in length L of the surface which increases the Reynolds number? Or is it more about how these dimples somehow cause irregularities in the flow and make the boundary layer turbulant?
"when you work on a subject long enough you will become god like and i saw a god in boundary layer subject today" . thank you i have a mid term on Monday
The authors have two wrong scientific approaches: researching the creation of Lift force and Low pressure at upper side of the wing, relative to the ground surface and Earth. I explain the aerodynamic cavitation and existence of Lee side aerocavern, and creation of Aerodynamic force. Low pressure creates force normal to the cord (contact surface), and it name is "aerodynamic force" because is made from the air (aero) in motion (dynamic), or wind relative to the wing (object).

Thanks a lot!

@@AirShaper fantastic thanks for sharing. The air blades by Nike are incredible, mini vortex generators ha
Was struggling to understand this concept ... but now its Fluid... thanks !!!
Thank you very much Vivek, I'm glad our video helped!
It's laminar .... smooth...
Is there sound issue?
Hi Wakas,
Yes, next time I'll increase the gain for the recording!
For now, turn up the volume if you can 🙂

Awesome. Thanks
Thanks Veyron!
Thanks a lot.
Thank you sir!
You're welcome!
TQ .buy . increase volume
Can't hear ...

audio is not good... I have max volume on my pc and on youtube and can barely hear
Yes, that's correct, we've increased the volume on more recent videos!
A bit oo quiet. My volume was on maimum but I old not hear it whilst steps away.
You are right! We've improved this on more recent videos
I cant understand it .
Please hire me as your intern
Hi Deepak, we don't have any open positions at the moment. Once we do, we'll post them at airshaper.com/jobs
