- In this video, we will derive the oblique shock (OS) relations. We will start from integral conservation equations, and derive expressions for the downstream Mach number, density ratio, velocity ratio, pressure ratio, and temperature ratio.

Hi Josh !
I was thinking about the Oblique Shock of the rocket nozzle yesterday (overexpanded/underexpanded).
Then, you give me the derivation for this today, I am so lucky!!!
Thank you XD.
My pleasure! I made this video in preparation for my discussion on overexpanded flow that I'll be doing in the next couple of weeks hopefully.
I never understood why the tangential component of velocity stays the same across an oblique shock.
It almost seems obvious now, thanks!
You're welcome! I'm glad this helped!
Great video! Thanks Josh
You're welcome!
Thanks so much Josh! I have my compressible flow final next Monday and you're helping me understand the material so much better. Just a quick question: was this course a part of your undergraduate curriculum?
Thanks Ben! Glad I could help. Yes, we had an undergraduate compressible flow class.
@@JoshTheEngineer Thanks for everything! Will spread the word about your channel to my friends.
No problem! Thanks for spreading the word.
Hi! Great video!! What about Method of Characteristic for the oblique shock?
Thanks! I'll be going through a full derivation and application of the Method of Characteristics in a future series for sure.
Wow!! That would be awesome😎.
hello jhos,, it would be nice if you put subtitles in english for people who do not master the language well. Excellent video
That's a good suggestion, thank you! I don't have much extra time on top of making the videos so this is tough for me to do. Also, the auto-subtitles that TH-cam can do are pretty bad, and would probably make it more confusing.
Where can I find the complete derivation of the equations at 16:34 sir?
I'm guessing you're talking about the normal shock relations? Here's my video on those (from the video description): th-cam.com/video/pR7mWvDWEJY/w-d-xo.html
Ok thanks sir. One more question. In oblique shock, prandtl relation is also a*^2 = (u1)(u2) ?
