nice video, I just want to ask on flow over plate, what is the meaning dp/dx=0??,. if dp/dx=0, then in flow over plate, separation will not occur even we extend the length of plate ??

Dear Fajar, dP/dX = 0 relates to the overall flow, where the velocity is constant. Because of the bernoulli equation, this means the pressure is also constant. However, you are right, this is a simple approximation. Because of friction (which indeed increases as the length of the plate increases) the pressure can indeed vary as you travel along the plate. And, as the boundary layer grows thicker, you can have a transition from laminar to turbulent at a certain point. This video is also quite interesting kzitem.info/news/bejne/lrCCqaOcfYWlkoY

In the 2:05, you mentioned that " If the pressure gradient in the horizontal plane is positive or zero, velocity gradient in vertical is positive." but it looks in the image and from the knowledge it must be negative pressure gradient right?

Would it be sensible to make surfaces more complex with sensors like shark skin that can adapt to the given positive or negative flow?

There is definitely a growing interest for "shape morphing" objects that can change shape in function of the aerodynamic goals. Or flexible materials, that deform under aerodynamic loads.

What would be the best shape if I want to maximize friction
@AirShaper
2 жыл бұрын
Hi David, we haven't had that question before :) Surface friction goes up with velocity, viscosity, surface area, surface roughness ... so those would be the parameters to work on. Keep in mind that you may trigger separation, creating a turbulent flow which has different friction properties as well.

why does the curvature influences on the pressure gradient in streamwise direction?
@AirShaper
Жыл бұрын
Dear Josué, I don't think I fully understand the question - if by streamwise direction you mean the flow lines, the pressure changes as the air slows down & speeds up (linked to the Bernoulli effect). What do you mean with the streamwise direction?

Mistake: If the pressure gradient is NEGATIVE or zero, then the velocity gradient in the vertical direction is a positive one.
