I'm fairly new to OpenFOAM and CFD simulations and I'd like to ask some questions and hope to get some directional advice on how to simulate a setup of multiple propellors.
The idea I'm working on is very basic, 16 rotors are placed in a circle, and drive by an internal motor, and RC controlled. The goal is to see if the whole formation would spin around its axis like a wheel, and move sideways forward through water, like drill.
I have been constructing a mechanical model to figure it out, but recently I've encountered some difficulties and thought of making the switch to a computer simulation. See pictures and clip below to get an idea.
The concept is based on a wild idea of how would physics-particles, such as electrons or photons would move through an Aether (the Vacuum) if they had any structure. More than a year ago I posted some rather naïve questions of CFD simulations at the speed of light on this forum and got some good advice to try to use Blender 3D.
Now I have tried Blender and even designed the model you can see in the pictures with it, but couldn't find a way to do a simulation with their physics engine, that's why I'm passing by OpenFOAM again to hopefully get some new advice from you experts.
So what I would like to know if its possible to simulate the motion of these propellors in a medium with OpenFOAM, and if it's doable, regarding rendering times, with a 'normal' computer?
Looking forward to hear from you,
A little sketch of the original idea:
The mechanical model in action:
How it's driven by little motors from the inside:
The technical design:
For a CFD simulation a basic setup would be sufficient:
Dance…even if you have nowhere to do it but in your own living room.
