    "title": "Jayden HARMAN - Vortical Flow Impeller - Pax Scientific",
    "inventor_name": "Jayden Harman",
    "publication_year": null,
    "device_name": "Vortical Flow Rotor",
    "goal": "Improve fluid flow efficiency by reducing turbulence and friction through vortex-inspired geometry.",
    "problem_addressed": "Conventional nozzles, diffusers and venturis suffer from turbulence, frictional losses and cavitation, leading to reduced efficiency and higher pressure drop.",
    "concept_summary": "The invention applies the Streamlining Principle, using geometries based on the Golden Ratio and logarithmic spirals to create an active surface that induces rotational and vortical motion of fluid within a nozzle, diffuser or venturi. This geometry aligns with natural fluid flow patterns, reducing turbulence and friction and thereby increasing overall hydraulic efficiency.",
    "detailed_description": "The patented flow controller comprises a duct (nozzle, diffuser or venturi) whose internal surface follows a logarithmic or equiangular spiral, often modeled on mollusk shell shapes. The cross-sectional area varies logarithmically in accordance with the Golden Section. As fluid passes, the active surface imparts a rotational motion about the axis, producing a vortical flow that is more laminar and less turbulent. The design can be realized as a simple conical outer shell with a complex inner spiral surface. The invention claims that such geometry reduces pressure losses, cavitation tendency, and friction compared with conventional straight-sided devices.",
