De Harmonia Motus: A Study on the Law of Flow and its Application to a Rotary Piston Engine inspired by the DNA Double Helix

"De Harmonia Motus" presents a conceptual synthesis based on the geometric principles introduced in previous works : Il Principio di Selezione Cinematica: - Principio ANNA - Una Legge Geometrica per l'Efficienza Universale Il Principio ANNA per la Conversione Cinetica Efficace: La Costante Universale di Equilibrio Perfetto Il Principio di Compattazione Geometrica: Un Modello Predittivo per l'Asse del B-DNA ANNA: A Generative Algorithm for the Axial Structure of B-DNA based on a Golden Disphenoid ηφ: A Characteristic Length for Discrete Golden Growth in R3 The Golden Disphenoid ANNA: A Three-Dimensional Constant from the Golden Ratio From the ANNA Tetrahedron to the Double Helix: a Modulated Golden Screw. It explores two paradigms of mechanical harmony ('Harmony of Equilibrium' vs 'Harmony of Flow') , using kinematic simulation and fluid-dynamic validation protocols to propose the ANNA Principle as a universal law for efficiency, particularly in fluid dynamics. This document serves as a 'manifesto' connecting the author's technical findings on the Golden Disphenoid ANNA to broader engineering and philosophical implications.Supplementary materials include the Python script implementing the CFD validation protocol described in Chapter 6.
