Plasmas-in-lquids heating in a mm-sized bubbles multiphase thermochemical rearctor

ORAL

Abstract

Energy production that is based on plasma-in-liquid multiphase reactions is an emerging and active area of research in the plasma science. For example, and as in the early days of testing fusion energy production, there were successful proof-in-principal devices that were based on plasma-in-liquid interactions. In this paper, a description of the design of a multiphase thermochemical reactor shows the efficient coupling of modern high power sub-Terahertz radiation sources heating to many forms of liquid & liquid solutions mm-sized bubbles to generate dense and hot plasma-in-liquid in the reactor. Furthermore, new compact and high magnetic field intensity elements that are based on commercially available superconducting technologies are properly configured in this reactor column design, and they support the feasibility of this energy production construct. In addition, the role of external heating elements in initiating the overall reaction process and in assisting to control it is highlighted. This overall design, while simplified by description, is scalable. However, it will be shown that actual experimental testing is to be carried out only after a careful analysis that includes design-of-experiment techniques.
