Abstract

This paper develops an early constructive realization of fluid-like dynamics within the Coherence Geometry framework. Fluid transport, rotational structure, pressure projection, dissipation, amplitude localization, and torsional response are organized through coupled coherence fields and Source-level geometric structure.

The construction uses potential and rotational phase channels, amplitude-weighted transport, non-local pressure projection, ripple diffusion, hyper-viscosity, torsional coupling, and related coherence-geometric mechanisms to generate fluid-like behavior.

Numerical investigations explore coherent rotational structures, interacting vortices, filamentary evolution, and vortex-shedding-like behavior. These calculations are presented as exploratory realizations of the framework rather than as claims of term-by-term physical equivalence with every mechanism of classical Navier–Stokes dynamics.

The September 2026 revision preserves the original numerical investigations while clarifying their interpretation and their relationship to the completed coherence-geometric fluid formulation developed in subsequent work.

Summary and Notes

Scope:

This paper develops a structured coherence-geometric analogue and generalization of fluid dynamics using coupled amplitude and phase structure rather than beginning directly from a conventional fluid state.

The construction organizes several familiar fluid-like behaviors through distinct coherence-geometric ingredients, including:

  • potential and rotational phase channels;
  • amplitude-weighted transport;
  • non-local pressure projection;
  • ripple-mediated diffusion;
  • hyper-viscous dissipation;
  • torsional coupling;
  • coherent rotational structure;
  • vortex interaction;
  • filamentary evolution; and
  • vortex-shedding-like behavior.

A central feature of the work is the separation of Source-level organization from the downstream appearance of familiar fluid behavior. The numerical examples demonstrate that coupled coherence fields can organize rotational and transport structures resembling fluid-dynamical phenomena without requiring every model component to be identified term-by-term with a conventional Navier–Stokes mechanism.

The computational investigations include interacting vortex configurations, rotational structures mediated by ripple-like fields, filamentary evolution, and amplitude-weighted vortex-street behavior.

These examples are exploratory realizations of the framework. They should not be interpreted as establishing complete physical equivalence between the early computational model and classical fluid dynamics.

The September 2026 revision therefore serves two purposes: it preserves the original constructive experiments and places them within the more mature Source-level and projection-based understanding of fluid dynamics subsequently developed in Coherence Geometry.

Within the larger research program, the paper provides an important historical bridge between early constructive fluid experiments and the later mathematical treatment of Source current, exterior curvature, projection, transport, viscosity, and observable fluid realization.
