I'm working on a physics simulation in Blender, but the Bullet engine implementation is far to underdeveloped for the concept that I want to realize. Therefor I'm posting her in yours Newton Game Dynamic forum with 2 questions:
- Is it possible to set up a 3D volume with viscoelastic-particles like in this clip at 2:38
http://www.youtube.com/watch?v=pyzvV8LwS-Y
- If so, would it be possible to have a freely moving propeller (torpedo) steering up these gaseous particles, within the volume, and being pushed forward, similar to the paddle-boat in this clip:
http://www.youtube.com/watch?v=hfmg0uRcHBY
The reason for those 2 questions is because, I'm working on a Science-Fictional concept of physics particles (electrons-photons), that are Torus or 8-shaped mechanisms. And I'm looking for a way to simulate the behavior of them as rotor-systems in a bath of particles (Aether). It sounds a bit complicated and too far-out, but it is actually a simple logical build-up.
Here's a short introduction:
The starting point of the idea are toruses that have a screw like structure, because of the rotation of this screw-like structure, and the hole in the middle of the toruses, these toruses have a suction power and a global rotary direction (see below text for links to images).
At close proximity the rotational movement of the spiraled construction of the toruses, generates some nearby turbulence that forces an other torus to be pushed away, and preserving them from getting entangled. But when some pressure is applied, and when they are properly aligned than the toruses could combine their suction forces and start drafting behind each other, and form a bundle (pile).
Because of the global rotary directions, these toruses can only rotate in certain harmonious directions with each other, and thus only a few basic shapes of combined piles can be formed. These structures would be spine-like and would swim around in a medium like a snake, twisting and turning and eventually, if they get to be long enough, able to biting its own tail, and forming a new Torus-structure. The whole process would behave as a fractal where toruses become new toruses (strings).
Here are some short animations:
Torus:

http://youtu.be/ExIBNeJqbzY (Lift-off)
I'm also working on a real mechanical machine to try out in water:
http://youtu.be/A53CEmaR8J0
The first rotor-constructions and Torus animations were made in Blender, and I wanted to have them spinning in a bath of particles, but Blender's Bullet-physics-engine isn't able to handle the job. So I asked José Jahkr who had a clip on YouTube with a simulation of a simple X-shaped 'mixer' in a bath of particles, if it would be possible to throw the mechanism in his bath, and see if it would spin and paddle forward. As only the principle is important, he didn't use the rotary system, but used a more basic setup. Here you can see some of his simulations:
http://www.youtube.com/watch?v=5XF58rtCYyo
http://www.youtube.com/watch?v=ndQDWQmgejc
These animations give an indication that it works, but the physics engine that he has written is limited, as he can only set the Torus at a fixed position. So the next step is to look for a more deep solution that can handle this set-up, whereby the Torus can move freely like the paddle boat in that YouTube clip.
The reason for my second question regarding a Visco-Elastic fluid, is because I have a hunch that due to the pressure of the gas, a torus that is given a push (impulse), could keep on spinning automatically forward, instead of being driven from the inside. Here for the principle is, that the inside of the Torus (O), in combination with the spirals, generates a closed area, of changing low and high pressure, where particles from the outside are pulled into, and compressed within the ring (O), and are blown out again. It would be a continuous process, a bit like a combustion motor.
Sorry for giving so much (chaotic) information at once ... please take a little time to digest it, and I'm sure that y'all get a grip on it, and if you have some questions please feel free to ask.
As you'll probably have noticed this isn't a commercial project but rather a curiosity driven thing … and so I'm looking for a particle expert that would like and could give it a go. At a first step just with 'normal' particles and later if possible with disco-elastic ones. I don't think that it is a lot of work to set it up, tweaking and rendering will be the most time consuming. I know its a bit of a wild idea, but if it works some cool things could come out of it.
One of the goals is to try out the Double-slit experiment:
http://www.blacklightpower.com/theory/DoubleSlit.shtml
... and test the idea of the 'Pilot Wave' concept of Bohmian Mechanics:
http://www.mathematik.uni-muenchen.de/~ ... startE.htm
I'm hoping that I haven't scared anyone, and I'm really looking forward to hear from one or all of you, and your experts view(s).
kind regards,
michel

Here ares some notes and images regarding the idea:
--
The basic torus formation is build up out of 2 x 4 tori squares <><>
The Blue & Purple ones spin in an opposite direction than the Red ones.
The reason for this set-up is that all Tori should spin together in harmony. If they would be in triangles, two of the 'touching' tori would rotate in the same direction (clock-wise) and cause friction.


These basic formations were placed in a circle 360° / 2.5° = 144 sets (Bx)
Each following set (Bx1, Bx2, Bx 3... Bx144) was given a twist (2.5°) around its center axis (0°, 2.5°, 5°, 7.5°, ..., 357.5°) so they fit nicely around the circle. This number could be changed to 5° or 7.5° etc. depending on the number of tori used per 360° , and by doing so changing the number of twist. The important thing is that they end up with at least a 180° twist, so they close the loop fluently.

--
Two images from José's animations, he used a 3-scoops setup. Note, the whole Torus doesn't move, it are only the 'steps' that rotate around their position, thats why the scoops are in RGB, and only half a torus, so it is visually clear that it stands still.


--
A first rough sketch of the concept:

--
The mechanical prototype to try out in water:

Because of the shape of the rotors they are also a paddle wheel like a 'Mississippi steam boat' and thus the whole would move sideways forward as shown with the big arrow, in the next image at point d. Forward movement of the New Torus


--
Here the model is given a black & white coloring to mark the spinning in water:

--
The mechanical designs:




---
These are images of how a pile takes shape:
Toruses have a suction power and rotational spin, due to drafting they can combine into a solid structure that is bendable:

Because of flexibility each base can phase-shift a few degrees and when completing the circle, twists would be generated along the circular curve:

These spines can twist and turn until they complete the circle like an ouroboros:


--
A simulation could be done in a regular volume (cube), but also in a closed tube. A spinning torus could than be placed at a fixed point and flow could be measured, or 'et go so it could move freely around.

For the medium in which the torus is places, a few colored particles (markers) could be added to visualize the currents, while all other particles stay blank, so the Torus can be observed.

--
The next step would be to see if two tori that are pushed together would align, but still push each other slightly away because of their rotary motion, and join their currents, connect, and becoming one:

--
An other test would be to see if an '8' formation would spiral forward, like a fastener:

--
The original idea for using an '8' came from a wooden windmill spiral thing, which uses simple sticks. José used a similar construction to set up his torus with 3 spikes.

The Double-Slit Experiment

p.s. I know less is more, but I thought I give it you all, all at once ... at the end it just about a basic rotaring Torus in a bath of particles moving forward.
