Phase-Locked Bubble Transport II: Numerical Exploration and Analogue Experimental Pathways

This preprint develops a numerical and experimental testing framework for the speculative transport concept the author calls phase-locked bubble transport. In this framework, a vehicle is modeled as remaining dynamically confined inside a moving low-gradient “bubble” formed by a driven traveling potential and remaining phase-locked to the motion of that bubble. Building on the minimal model introduced in Part I, this paper focuses on numerical simulation and analogue validation pathways rather than theoretical motivation. A closed-loop vehicle–wave interaction term is introduced to represent the vehicle’s role in stabilizing and steering the bubble. The combined equations form a coupled first- and second-order nonlinear system. Suggested nondimensionalization, parameter sweeps, and stability-region mapping procedures are provided to enable reproducible numerical testing. Two analogue experimental implementations are proposed: (1) a bead trapped in a traveling acoustic potential generated by a phased speaker ring, and (2) a conductive puck transported along a low-friction track by a phased electromagnetic coil array. Measurement targets include phase deviation, capture probability, and lock-bandwidth as a function of drive sweep rate and damping. This work does not claim technological feasibility or reactionless propulsion. It is presented as a mathematical and experimental exploration of whether sustained, phase-locked transport inside a self-generated traveling bubble is dynamically consistent within classical physics. The author invites independent critique, modeling, simulation, and laboratory testing.
