Source/Sink Flow (Incompressible Potential Flow)

- This is the next elementary flow after uniform flow. We will start with the velocity potential (without derivation), and then compute the Cartesian velocity components. We will then go through a script to compute the flow-field due to a source/sink, and compute the circulation around an arbitrary curve.

It is really helpful, Thank you so much. Where can I access this code for MatLab?
Hello I am stuck on a question, there is a source and sink , the question asks what happens when Q(source strength) approaches infinity and d(distance between the source sink) approaches zero. I asks me to prove the the velocity potential is equal to k(cos(theta)/r where k is equal to Qd/pi . Really stuck on this quesions any help is much appriciated
Thank you so much for nice video. However, I want to know what is import file "COMPUTE_CIRCULATION"? What is the data you imported? Thank you
You're welcome! That's just a function file, which you can download from my GitHub (github.com/jte0419/Panel_Methods). I write all my function file names in all caps, so if you see that in my future videos, they're just external function files. You just need to have them in the same directory as the main script.

How do engineers optimize flow through an axial compressor? Or even between different types of compressors, like an axial vs centrifugal. Its like black magic!
I don't know much about the details, but for starters, you can do a search for "compressor velocity triangles". Might be a good jumping off point!
