Feasibility and Performance of Magnetic Theromosyphon with Magnetic Fluid in Non-Gravity Field

A new thermosyphon using a magnetic fluid as the working fluid has been proposed for heat transport in a non-gravity field, and named "magnetic thermosyphon". A magnetic body force drives a liquid phase flow, and separates vapor and liquid phases in the magnetic thermosyphon. It has been found that a liquid bypass line between a heat input section and a heat output section is required to return a highly concentrated magnetec fluid from a boiling region to a condensation region. The thermohydrodyamic feasibility of the magnetic thermosyphon has been confirmed analytically. The performance of the magnetic thermosyphon has been evaluated, and as a result, the relationship between heat transport rate and liquid mass flow rate under steady-state operating conditions and a maximum heat transport rate of 65.5 W has been obtained for the present thermosyphon model.
