In summary, The conversation discusses two experiments, one about boundary layers on a flat surface and one about pressure distribution on an airfoil at different angles of attack. The person also shares a link to a cool diagram explaining why birds fly in a V formation and suggests using online resources such as Wikipedia and Google for more information on these topics.

Hi people, i am really in a deep trouble and i will be so happy if anyone can help. Any tips will be so appreciated and make a real different to what i am going through at the moment. i have got two question to answer.

1. Experiment of boundry layer on a flat surface : giving dtails of how the boundry layer are formed

2.Eperiment of pressure distribution on an airfoil at differents angle of attack

One cool airfoil diagram is the one that explains why birds fly in a V:

It means the lead bird and the 2 flanking birds do extra work, but the everage of each bird's total work is reduced by a huge percentage. And about boundary layers, are you talking about the fluid surface separating 2 mediums? There is a lot of info online about both these topics. Try Wikipedia.org first, and be sure to look at the references and external links at the end of each article. Then try google...

Hi there,

As an aerospace engineer, I understand the importance of these two experiments in understanding the aerodynamics of a flat surface and an airfoil. Let me try to provide some tips that may help you with your assignment.

1. When a fluid flows over a flat surface, a thin layer of fluid near the surface experiences a decrease in velocity due to the friction between the fluid and the surface. This layer is known as the boundary layer. The formation of the boundary layer can be explained by the concept of laminar and turbulent flow. At the leading edge of the flat surface, the fluid flow is mainly laminar, meaning it moves in smooth layers. As the fluid moves along the surface, it starts to transition into a turbulent flow, where the layers of fluid start to mix and create chaotic motion. This transition from laminar to turbulent flow is known as the boundary layer transition.

2. The pressure distribution on an airfoil at different angles of attack is crucial in understanding the lift and drag forces acting on the airfoil. At a low angle of attack, the flow over the airfoil is mainly laminar, resulting in a smooth pressure distribution. As the angle of attack increases, the flow separates from the airfoil, creating a larger wake and a turbulent boundary layer. This turbulent boundary layer causes a higher pressure on the upper surface and a lower pressure on the lower surface, leading to an increase in lift and drag forces. By conducting experiments at different angles of attack, we can determine the optimal angle for maximum lift and minimum drag.

I hope these tips will help you in understanding the concepts behind these two experiments. Remember to also consider factors such as Reynolds number and flow velocity in your analysis. Good luck with your assignment!
