Aerospace Engineering Experiments

[moust]

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

You haven't asked any questions. You have only made comments. It's tough to provide answers when no one but you knows the questions.

Hi there, sorry to hear that you're going through a tough time. I'm not an expert in this field, but I'll try my best to help with your questions.

1. As far as I know, boundary layers are formed when a fluid (such as air or water) flows over a solid surface. This layer is created due to the difference in velocity between the fluid and the surface. It can be divided into two parts: the laminar boundary layer and the turbulent boundary layer. The laminar boundary layer is a smooth and orderly flow of fluid, while the turbulent boundary layer is chaotic and has a lot of mixing. These layers play an important role in aerodynamics and can greatly affect the drag and lift of an object.

2. I'm assuming you're referring to an experiment where you measure the pressure distribution on an airfoil at different angles of attack. This is usually done by placing pressure sensors at various points on the airfoil and then changing the angle of attack (the angle between the airfoil and the direction of the incoming air). As the angle of attack changes, the pressure distribution on the airfoil will also change, which can be measured and recorded. This information is important in understanding the aerodynamics of the airfoil and can help in designing more efficient and stable aircraft.

I hope this helps, but I would recommend consulting with a professor or someone with more expertise in this area for more accurate and detailed information. Best of luck with your project!
