Can constrained pressure make liquid flow without a motor?
Start with liquid under uniform high pressure in a closed angular torus and the membrane geometry selected by V10. The first run applies no pressure disturbance. The second introduces one small initial disturbance and then observes what happens when no further work is supplied. The model cannot quietly invent circulation.
Pressure and fluid motion are different. The torus is initially full of liquid at 10 MPa, but the uniform-pressure trial leaves it at rest. In the disturbed trial, a small, initially stored acoustic disturbance propagates along a stationary channel with V10-derived constrictions, fluid inertia, compressibility and dissipative losses.
The membrane geometry is imported, not redesigned. Copper voxels come from the exact V10 solid mask when selected on this website; otherwise the V10-generated fallback is explicitly labeled. Its anisotropic geometry enters a one-dimensional impedance approximation, not true membrane pore-scale CFD or deformation.
Electricity cannot emerge from static liquid. For the optional conductive-metal calculation, a simplified magnetically loaded section can extract a little of the finite acoustic energy, while exerting a braking force. This is not proof that stationary magnets and a closed vessel form a self-powered generator.
What's missing: a validated 3D velocity field, pore-scale anisotropic tensor, measured materials and vessel compliance, real electromagnetic electrode geometry, grid refinement and experimental evidence.
