Abstract
This disclosure describes a research‑stage concept for a Hybrid Vortex‑Resonant Seismic Isolation Module, a passive fluid‑structure interaction system intended to explore alternative approaches to seismic energy dissipation. The design uses an annular chamber with internal helical vanes to induce vortex‑based rotational flow, creating a phase‑lag between ground motion and fluid motion. Analytical modeling and finite‑element simulations suggest potential reductions in modeled structural acceleration when tuned to building‑specific resonance frequencies. The system geometry, vane parameters, and fluid viscosity are presented along with resonance‑tuning equations and a proposed validation roadmap including numerical modeling, component‑level flow testing, and shake‑table evaluation. All performance values represent simulations or bench‑scale analogs rather than certified structural outcomes. The concept is released under CERN‑OHL‑P v2 for research, humanitarian engineering, and open‑hardware development.
