Novel Thermodynamic Cycles Involving Ferrofluids Displaying Temporary Magnetic Remanence

Authors: Remi Cornwall

The objective of this research is to utilise the massive amount of low grade heat energy, for instance which exists in the worlds oceans, by a new type of magnetic cycle. Developed herein are methods based on 2nd order phase changes that make it possible to achieve high efficiency despite small temperature differences with the reservoir. Ferrofluids displaying temporary magnetic remanence are an almost perfect embodiment of the working substance for these cycles. Standard Kinetic Theory, Thermodynamic and Electrodynamic analysis validates the new cycle. Experiment, both physical and by numerical solution have laid the foundations for this work showing: that a property of the system is a strong function of temperature, that a temporary independent flux remains after magnetisation and that a cancellation scheme is required to achieve energy transduction in excess of the magnetisation energy input. This research shows that a new type of heat engine/refrigerator/heat pump is possible.

Comments: 92 Pages. Thesis. New version with newer refs, B-H (M-H) curve for ferrofluid loss, some cosmetic changes and minor change at start of chapter 4.
