Flow boiling heat transfer of binary mixed magnetic fluid

摘要

A new type of binary magnetic fluid, which is a mixture of base magnetic fluid with an organic secondary fluid, whose saturation temperature is lower than that of the base magnetic fluid, was introduced. Basic heat-transfer characteristics of the binary magnetic fluid were examined for boiling two-phase flow in a partly heated pipe. It was indicated that the continuous boiling was achieved without any deterioration in magnetic properties of the fluid and the heat-transfer rate of the flow was improved remarkably by applied magnetic field at higher flow rate.
