In the present study, the flow characteristics and heat transfer of a thermo-sensitive magnetic fluid, which is a multiphase-flow material, were investigated experimentally. The experimental results indicated that force convection based on the magnetic characteristics of the fluid in the mini-channel exhibited excellent cooling performance. In particular, the observed variations in the flow patterns were compared with the results of a boundary layer of the flow velocity in the pipe, which is generally known. And the relationships between the phase-change characteristics and the stability of the emulsion are discussed in detail on enhance for the heat transfer of the thermo-sensitive magnetic fluid flow. The experimental results reveal that the phase-change nano-emulsion, which has fluidity and heat storage characteristics, was a functionality material.
