Fluid Motion Simulations and Artwork

When a droplet falls into shallow water, it creates a crown or "coronet". This droplet simulation was calculated using Smoothed Particle Hydrodynamics (SPH). SPH is one of the most impressive-looking fluid simulation techniques.

Oscillon Astonishingly, oscillons of opposite phase will attract over short distances and form 'bonded' pairs. Oscillons of like phase repel. Oscillons have been observed forming 'molecule' like structures and long chains. In comparison, solitons do not form bound states. Stable interacting localized waves with subharmonic response were discovered and named oscillons at The University of Texas at Austin. The cause of this phenomenon is currently under debate; the most likely connection is with the mathematical theory of chaos and may give insights into the way patterns in sand form. The experimental procedure is similar to that used to form Chladni figures of sand on a vibrating plate. Oscillons have also been experimentally observed in thin parametrically vibrated layers of viscous fluid and colloidal suspensions. Nonlinear electrostatic oscillations on a plasma boundary can also appear in the form of oscillons. See also[edit] Cymatics References[edit] Further reading[edit]

Thank you,I,ve placed it into my pearltrees. I very much appreciate this. by ixgagbalamvucub Mar 18

Thanks I was working on that today I'll send you the link ;-) by mirlen101 Mar 17

I think that it would be an excellent idea to create a pearltree dedicated to these different classes of waves as in one way,or another they are interconnected. This may very well end up being a large pearltree, as there is a large amount of very interesting information on particle waves,the behaviour of particles when observed,as versus unobserved,which inturn has an effect on how the particle waves themselves are formed. The subject of particle waves themselves would consist of several informative,and fascinating pearls. by ixgagbalamvucub Mar 17

Ned worked on exhibits at the science Exploratorium in San Francisco before going out on his own as an architechtual artist.The Exploratorium is an awesome place for cool science exhibits .
The "wave theory of everything" will be wide in scope . Physics , art , education , fluid dynamics , sound waves , brain waves , light waves etc. I started one in an art section and another in a brain science section . I'm going to keep those going but I wanted to do one with a wider scope using all three . Mind , physics and art etc.. I guess I should start it in the physics pearltree .
Be great to have you on board ! ;-) Your input will be greatly appreciated ! Especially on sorting out the flow , structure of categories . by mirlen101 Mar 16

Love the wind veils of Ned Kahn - very specky! It's a great direction to take a Pearltree on Wave Theory . . . the curatorial nature of this application must be dynamic for its full effect. I'll look forward to your new Pearltree and hope I can Team Up on it. I'll provide a branch on Solitons. by pauljacobson Mar 16

I have wave theory pearltrees in at least 3 separate sections . There's sound waves , fluid waves, particle waves , light waves , gravity waves, art based waves ( like VFL , video feedback loops ). The list keeps expanding out and cross linking . Wave theory is getting to be way more popular in research . Really amazing things coming out of it . Especially brain wave research ! It is mind blowing stuff ! ;-)
I'm going to have to start a new wave theory pearltree just to tie it all together ! by mirlen101 Mar 14

Hi dmoton - this is fantastic! The beauty of mathematics comes to the fore in complexity. I have picked this pearl for continuing reference. Back in the 90s I was very proud of my computer graphics in Photoshop of scenes underwater back lit by rays of light (and ripple effects). All algorithms. by pauljacobson Mar 14
