Can two toroidal devices help each other?

Real four-bar linkage closure drives changing membrane chamber volumes. Computed pressure, startup flow, electrical current, coil coupling and input/output energy are compared across five arrangements. The simulation runs on your device.

Engineering model, not a working generator. The chambers use simplified check-valve diaphragm pumping. Most paired cases have one hydraulic loop per torus. The two IN SERIES modes instead connect moving chambers into one closed circuit using finite-volume continuity and ideal one-way valves. The 90° field coupling is a symmetry approximation; real magnets and membranes require measured properties and field/FSI solvers.

Copper voxels are actual V10 solid material; blue voxels are voids. The displayed slices are the source's static 3D topology, not a new synthetic torus mesh. Their modeled through-flow resistance now changes the torus calculations. Iris compression is applied separately to the outer moving chamber; a combined deforming 3D membrane/CFD model is not solved yet.

The paired independent-loop cases use two separate fluid circuits; the two IN SERIES cases share one closed flow path and test opposite versus synchronized moving walls. Every case includes two powered iris drives and motor losses. Total flow between these topologies is not directly comparable.

What the model actually moves

The four-bar crank and coupler are solved from mechanical link lengths at each input angle. The follower drives a membrane aperture approximation, changing actual chamber volume. Each head has a calculated suction or discharge rate from its volume derivative. In the IN SERIES experiment, two moving volumes obey separate mass conservation equations, linked by two directed ideal check valves around one closed fluid circuit. The imported original V10 solid/void geometry (or labeled V10 fallback) now supplies a matched-grid hydraulic conductance ratio, which modifies the simulated torus resistance. The generated flow drives hydraulic inertia and magnetic braking.

Displayed membrane strokes are visually enlarged to be legible; actual radii are in the numerical receipt. A check valve is idealized, with no unresolved reverse leakage.

90°, north/south and opposite rotation

90°: The idealized coil mutual inductance approaches zero in the chosen symmetric arrangement; this can reduce coupling rather than amplify it. North facing south / inverted: Reverses electrical polarity and changes mutual interactions, but output still requires mechanical pumping energy. Counter-rotating: The second iris crank turns backwards, altering phase and pulse timing; fluid direction is separately set by the ideal check valve.

The alternating IN SERIES pair initiates forward flow from rest in the numerical circuit; synchronized strokes provide the control. The test tracks coil magnetic energy, membrane compliance and fluid kinetic energy. No free spin-up or efficiency gain is awarded.
