thanks man

sorry if this is a silly question but why is the d not squared for dphi/dydz and all the others?

I got lost after good morning everyone

I saw your video repeatedly, and thank you for this Gold Mine, I have a question when I go to the steps on making that loaded file to be deleted on the Matlab code the comment "% Delete files if they exist" and "delete(saveFlnmAF); " parts, when I uncomment it and click RUN it is saying to error "Warning: File 'Save_Airfoil.txt' not found. > In MATLAB_XFOIL (line 52) Undefined variable 'dataBuffer'. Error in MATLAB_XFOIL (line 55) XB = dataBuffer{1}(:,1); % Boundary point X-coordinate >> What should I do, I watched your video for the 5th time today and I can't see any difference that I am making to get this kind of error, and anyone who can help, Please

Thank you This Video helped me with my University Exam🙂.

I love how this guy just deduces that everybody that is curious enough to watch his videos must be a skilled matematician, capable of easily solving the last equation. He spent 7 minutes explaining how to formulate the damn equation then he just shows the result without even showing the process...

Talking fast is most of the time a sign of insecurity and not helpfull if you want transfer information.

Hii what kind of engineer are you?

Literally the perfect instructional video.

You saved my IB MATH HL IA, thank you so much really clear and straight to the point

Is there any intuitive analogy that Cp and Cv that we can relate this to in real life? So abstract.

Nice and simple explanation for something so complicated.

Thank you so much for sharing valubale information :)

Amazing video. I have a quick question, if you have the time. What is the minimum temperature difference that can be shown in this setup? Can heat rising from a human body be shown like this? Thanks very much.

one of the most harsh topic i have ever seen in engineering.

This is brilliant! I finished college many years ago, but I still use notebooks for notes on books I'm reading so I won't forget. I've made "cheat" sheets for my son, who is dyslexic, on books he has to read for school with characters' names, settings, events, maps, and pictures. Grid notebooks are my favorite.

Hey, do you (or anyone else) still know where i could find a viable source for the equation?

Thanks good video

I like how you get to the point immediately. The inclusion of the diffuser makes sense but is also kinda counterintuitive. The afterburners are there to increase the velocity of the gases but to utilize them optimally we need to slow down the gasses first. I imagine that tuning the diffusers must be quite a challenge. To have a design that results in the maximal net velocity gain.

This explanation really helped me.

Thanks...it's a really nice video..

josh i cannot hear you no one can

That's a nice system, I'm going to change to that system! Thanks !!!

this video helped me. thanks to the teacher

Thank you! I was wondering how to do this until I saw your video. 👍

The way you organise the tutorial and the board is so fascinating Thanks alot

Hi Josh, excellent video and I have learned a lot. I have a question where if the default location of the thickness is not 30% of chord but at 23% of chord, what is the thickness distribution equation? Thank you.

What if it is a wood log

How can we run parallel simulations? I tried but having problems here. Thanks for this tutorial

Great video, sir! Thank you very much ❤❤

Is this theory basically what Whittle came up with in his senior thesis?

Hi Josh. Do you have a good reference for pulsed supersonic valve?

you saved lives

cool!. what kind of filament did you use?

you make an awesome professor. thank you

How do the bags survive the blasting engines long enough to do any kind of job?

You are a legend

Life Saver!

What the 🤯

Thank you so much for such detailed video and explanation. I understood thoroughly. 😊

Can you speak a bit quicker please!

thanks for this video!! awesome!!! here my some more ideas, we can do this discrete data integration using sum(udx+vdy), capture the variables along the circle and just do the summation!!

I like your funny words magic man

I'm in Aerosapce Engineering, having a hard time wrapping my head around these shock wave formulas. How do they take into account an aerodynamic or bluff body, for example? Say if we needed to calculate those ratios at different stations around an airplane fuselage, in an engine with an aerospike, a hyperloop train, etc?

Brilliant video! Goes down to the real fundamentals of meshing.

Wow, very nice and informative video!!

It seems to me that for a symmetrical airfoil, you can get a surprisingly decent approximation with a half ellipse ending at 30% chord, then a tangent circle arc to hit the trailing edge at the centerline (not perfect, but close enough if you just need to draw a visual aid rather than plotting the airfoi). I wonder if the equations simply to something similar, or if it's pure coincidence

How much horsepower does a 2016 Challenger Hellcat At .356 drag coefficient at sea level (Kennedy Space Center) need to go 215mph? Will 1000whp get me there with proper drive ratio?

Excellent tutorial, thanks for the video!
