Feasibility and performance of magnetic thermosyphon with magnetic fluid in non-gravity field

A new thermosyphon using a magnetic fluid as the working fluid has been pro posed for heat transport in a non-gravity field, and named "magnetic thermo syphon". A magnetic body force drives a liquid phase flow, and separates va por 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 magnetic fluid from a boiling region to a condensation region. The thermohydrodynamic feasibility of the magnetic thermosyphon has been confirmed analytically. The performance of t he magnetic thermosyphon has been evaluated, and as a result, the relations hip between heat transport rate and liquid mass flow rate under steady-stat e operating conditions and a maximum heat transport rate of 65.5 W has been obtained for the present thermosyphon model.
