The Self Driven Heat Conveyer: A Phase Change Propelled Slug Conveyor for Passive, Orientation Free Heat Transport

Requesting collaboration on a proposed framework for a new type of self drive heat transfer device. There is no power required to move heat from one source and transport it to a cooling source. I have developed the concept and its features myself but have used Claude to develop the document (with edits from myself) and to perform the analytics on the concepts and features I developed. The Self-Driven Heat Conveyor (SDHC) is a proposed passive thermal-transport device: a closed tube loop containing a train of self-lubricating slugs separated by discrete cells of a two-phase working fluid. Cells partially vaporize and expand in the heated zone; cells condense and contract in the cooled zone; wall-mounted one-way features ensure travel of slug train in one direction. Because circulation is driven by phase change expansion rather than by buoyancy or capillarity, the device is predicted to transport heat passively in any orientation, including long horizontal runs. This paper presents the reference architecture; derives the governing selection rule for volume-constrained phase-change conveyors — the volumetric latent energy density of the saturated vapor; develops a first-order transport and self-sustainment model; and applies both to a reference design in saturated water at 200 °C, predicting on the order of 11 kW per 25 mm loop. No SDHC has been built at any scale. The paper concludes with a formal ledger of open problems — six in physics and eleven in engineering, each stated with what is known, what is needed, and a suggested first experiment — and an open invitation to collaborate.
