At 21:22 for clarification. is (x_i, y_i) the coordinate of the control point for the i-th panel? or the starting boundary point for the i-th panel, like (X_j, Y_j) is for the j-th panel?
Good question. Since we are solving for the normal velocity at the control point of the i^th panel, the (x_i, y_i) coordinates are always the control point coordinates. Since we are integrating over the j^th panel, we will be using the boundary point coordinates for the (X_j, Y_j) values. When I post my final video (and code), you'll be able to see that every (x_i, y_i) gets replaced with values I call XC(i) and YC(i), and every (X_j, Y_j) gets replaced with values I call XB(j) and YB(j). As you might guess, the C stands for "control" and the B stands for "boundary".
In the video (and on the board), I say that del is equal to phi plus 90. If you want to know why, please watch my "Panel Method Geometry" video (you can skip to 7:28 where I talk about it): ruclips.net/video/kIqxbd937PI/видео.html

This was fantastic! was reviewing numerical solutions to panel methods and going over this was everything i needed. You rock.
Awesome, thanks!
Thank you for this video. Was stuck on this problem for a long time.
Glad I could help!
Good ! This video solves my puzzle , Look forward to your next video , Surface vortex method
Thanks! Working on filming now.

@@JoshTheEngineer Great, looking forward to seeing your implementation. I've got my own nearly finished and working.
@@williamsworkshop8624 That's awesome. I'll be filming these final videos soon, and I'll post that code when I do.
hi , can you please help , how to calculate the cartesian velocity fron the normal velocity and how to program this integral , thank you
Thank you for the video! But why do we have to choose a control panel i instead of a control point?
Thank you so much.
Great video. Thank you Sir
You're welcome!
fantastic!
Thanks!
Perfect 👌
Thanks!
how often do you check your email ?
Probably once every few days. It depends on how busy I am.
Great😁👍
at 7 min 56 sec you say del = 90-phi why is this so
In the video (and on the board), I say that del is equal to phi plus 90. If you want to know why, please watch my "Panel Method Geometry" video (you can skip to 7:28 where I talk about it): ruclips.net/video/kIqxbd937PI/видео.html
Just saying......God bless You.
Thanks!
Wish I could have sexy professor like you in my college😂😂😂 I wouldn't be looking here and there so desperately to understand the topics.
CAN YOU TELL ME HOW CAN I EVALUATE THE LAMBDA FOR AİRFOİL. THANK YOU SO MUCH amk mühendisi
