This is very cool! Impressive stuff. One thing I'm curious about is how the fluid's velocity is calculated. Given that this model has an open top, there are significant energy losses that would otherwise aid in the fluid's flow. Would it be too difficult to re-run this simulation with a transparent cover? Thanks again for making an awesome vid!
Thanks John :) The fluid velocity is calculated based on the Navier-Stokes equation and no-slip condition at all surfaces, but please bear in mind that I did this simulation focusing on the computer graphics side of it and not so heavy on the computational part. Part of the reason why I left the top part open is to show the bubble, foam and spray particles formation from the FLIP method used in this simulation (as it is an extra aspect that might be of interest). And you are right, a lot of horizontal velocity will be wasted to the vertical axis as well. I was planning to redo this version again with the velocity field being plotted in the fluid itself, and I think I will add the transparent top cover as you recommended.
@Fluid Tomato , thanks for the rapid response! Oh! Now I understand, sorry. I didn't realize that the video was made to primarily showcase the graphics side of things. With that in mind, well done! I'm no expert, but it does look pretty faithful to life. I look forward to the follow-up video(s)! :)
@@CHZMN1 Well I aimed to have both scientific info and computer graphics in a video. But the fluid engine embedded in these graphic software is not to an advanced level, although you can kind of getting some useful info, but in terms of raw scientific data, these software does not do the justice. Like in these videos, you can grasp the idea of Tesla valve and how it works, but information about flow turbulence and drag force on fluid, it would require a pure engineering software I am afraid. Thanks for your comment!

that was nice way to demonstrate Tesla valve
this is a great water simulation!
Awesome!
Thanks for your comment!!! You got some cool CFD simulation there.
