Potential flow around an airfoil

AI Thread Summary
A user seeks guidance on simulating potential flow around an airfoil using Matlab, specifically inquiring about the feasibility of achieving a steady solution for subsonic, laminar flow. They express unfamiliarity with potential theory and aim to tackle an elliptic problem, hoping for a straightforward approach. Additionally, they request information on generating an elliptic grid, mentioning the need for a normalized airfoil shape and referencing NASA's airfoil profiles. Recommendations include consulting "Fundamentals of Aerodynamics" by Anderson and writing a vortex panel code for the simulation. The discussion emphasizes the importance of foundational knowledge and resources in aerodynamics for successful simulation.

I invoke those aero-brains flying around here in order to help me in these questions:

I want to simulate numerically using Matlab the potential flow around an airfoil. The first question is if anyone of you knows if is it possible a steady solution of such potential flow (subsonic and laminar) over an airfoil. To be honest, potential theory is not my best, surprisingly I have not learned it in my university. But I want to simulate an elliptic problem such this, in part because I think it might be easier, and I don't hope to start writing a computer program that has no steady solution.

Another question is the elliptic grid generation. I have seen it is necessary to solve a partial differential system of elliptic equations in order to generate it. So I will need some type of normalized airfoil shape. I have read that NASA has some series of such profiles. Those who are aero-heads surely know where can I found this shapes (that allow me to strum the coordinate transformations) in the web.

Any help will be wellcomed with a cool Duff beer sent by e-mail. :rolleyes:
 
Physics news on Phys.org
read fundamentals of aerodynamics by anderson chapter3 & 4. you need to write a vortex panel code. damn easy
 
Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
