XFOIL Boundary Layer Transition (Basics)
HTML-код
- Опубликовано: 20 авг 2024
- In this video: laminar vs turbulent flows, why we care where the flow transitions, the two methods XFOIL uses for predicting transition, a quick introduction to the e^n method (and Ncrit), and steps for changing where the flow transitions.

Series Description:
This is another video in a new series on the XFOIL software brought to you by the Science of Flight, a new brand on RUclips. Whether you’re an undergrad in an aero course or a working professional that just got placed into an aero role, this series is for you. Although the idea is to create an awesome lecture series to support aerospace engineering education, the hope is that this won’t just be a lecture series but when it is combined with other interactive content it can become an entire learning system to truly master XFOIL. If you have good ideas for apps, interactive virtual models, software, or even learning objects that could be 3D printed throw it in the comments below along with what topics you want to see covered. After you comment, check out the next video in the series.
Channel Description:
Since the beginning, man had looked to the sky only to have remained earth-shackled. Aerospace engineering changed all that in a very short 100+ years. The airplane has come a long way since the 1903 Wright Flyer and aerospace engineering along with it. If you look at a modern-day fighter jet it’s no wonder that nowadays aerospace engineering curriculum can be a daunting task. This leads to 19 credit hour semesters being the norm, fast pace classes, missed content, less interactive lessons, lower comprehension due to shorter discussions, and never enough time to read the textbooks. Combine this with thick accents, difficult concepts, and professors who care more about research than teaching and engineering education turns into a game of stamina instead of a game of wit. At the Science of Flight it is believed that excellence in engineering starts with excellent education and tSoF is dedicated to improving aerospace engineering education for the student as well as the working professional.

This is exactly what I needed to understand Ncrit! Thank you very much sir!
Glad it helped!
Your tutorials are great, thank you!
No problem. Let me know if there are any particular tutorials you'd like to see and I'll work it into the video lineup.
@@thescienceofflight1404 Hi, it would be great if you would do video on eN method and other parameters in vpar menu. I am currently working on optimization of wind turbine airfoils using genetic algorithm and Xfoil. I have designed couple of interesting airfoils on small Re number, but I need to include soiling effects in my design so it would be great if you could provide more information on eN method. Thanks in advance.
sad to see this website is no longer active
Very nice tutorials! I have used this tool in some aero classes, and still trying to improve myself on this low fidelity tool because so quick computation of aerodynamic performance can be helpful for me to use some optimization techniques during my master. Especially implementing the machine learning algorithms to get better performance from optimized airfoil design. If you have any article recommendations on this, it can be very helpful! Thank you for tutorials.
Great video! It was very helpful
Awesome, thanks!
@@thescienceofflight1404 Hey man, the website doesn't work anymore :(
Thanks a lot. But I looks like your website is broken. I can't access, please fix it
Thanks a lot
Happy to help!
Great video! Just one question that I couldn't find on the internet: how do I extract Boundary layer parameters (thickness, drag coefficient, form factor H, etc.)?
Hey, what happenwd to the Homepage?
I am trying to learn how to design airfoils myself and would be very interested in more videos like this!
Can you recommend any good literature to get going. (Preferably more hands on information on how to design airfoil for a specific purpose, rather than just the theory behind it)
