A small correction. A fluid tends to move from a high pressure region to a low pressure region, for instance the wing tip vortex. So, the adverse pressure gradient is when the fluid moves to a relatively higher pressure (dp/dx > 0), contrary to what was stated at 3:05.

📝 Summary of Key Points: 📌 The boundary layer is a thin layer of fluid that forms on the surface of an object as it moves through a fluid, caused by friction between the fluid and the surface. 🧐 There are two types of boundary layers: laminar and turbulent. Laminar boundary layers reduce skin friction drag and improve aerodynamic efficiency, while turbulent boundary layers are thicker and cause more skin friction drag but can withstand adverse pressure gradients and prevent flow separation. 🚀 Understanding the boundary layer is crucial for optimizing the aerodynamic efficiency of objects like aircraft wings and sports equipment. 💡 Additional Insights and Observations: 💬 "The boundary layer only forms in a viscous fluid." 📊 Laminar boundary layers reduce skin friction drag, while turbulent boundary layers cause more skin friction drag but can withstand adverse pressure gradients. 🌐 References and Sources: The video does not mention any specific references or sources. 📣 Concluding Remarks: The boundary layer is a significant concept in fluid dynamics that affects the movement of objects through fluids. Understanding the different types of boundary layers and their impact on drag and flow separation is crucial for optimizing the aerodynamic efficiency of various objects. Made by Talkbud

Hello, what I do not understand is why you said laminar boundary layer is to reduce the drag at first, but then gave an example of golf and tennis ball that holes on them were made to create turbulent flow to reduce drag. I feel lost on the concept that its is turbulent or laminar flow which can reduce the drag. Hope you can answer me , thank you !
@Airlynch0772 жыл бұрын
do you mean the pressure drag creating by turbulent flow for golf and tennis, but skin friction drag creating by laminar flow, there are two different drags which may make sense.
@JxJAVIATION2 жыл бұрын
If we consider a smooth body, a laminar flow is required since it will stick to the surface, however if we consider a bluff body a turbulent flow is required, which will cause the flow to stick to the surface! This will reduce the drag!! Hope it helps!

@@Airlynch077 In case of balls, the flow separation is worse than the added drag for a turbulent boundary layer. Since we can't make them not balls, that's our best bet. For everything else just avoid flow separation

At 1:32 , why does the speed of the air particles gradually increase?
@JxJAVIATION2 жыл бұрын
Because of friction the speed of the particle sticking to the surface is zero, as we move further the friction is no longer applicable so the speed increases.

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).
