CONFINEMENT ENERGY. Serrano Principle: Work Amplification in Incompressible Fluids through Volumetric Confinement

This document presents Confinement Energy as a new paradigm in incompressible fluid hydraulics, formalized through the Serrano Principle. This principle establishes that, within a closed enclosure of variable geometry, the work that must be supplied by an external source to expand the enclosure is proportional to the difference between the expansion volume and the volume inserted by solid elements (plungers, pistons, rods). The remaining fluid, by not being evacuated in each cycle, acts as a passive energy transmitter, allowing the external source to supply only the volumetric differential. The principle is summarized in the equation K = 1 / (1 - η), where η = ΔV_solids / ΔV_chamber is the Confinement Coefficient. The higher η is, the greater the amplification factor K becomes, with no thermodynamic limit beyond losses due to compressibility and friction. Experimental data are presented for the Notatus Motor, a prototype that applies this principle and achieves an amplification factor of 9.16 (bench-tested), with projections to reach a factor of 20 and even higher levels through geometric optimization.
