Heat transporting characteristics are investigated experimentally for a heat transport device using a temperature-sensitive magnetic fluid. In the present study, in particular the regenerative thermomagnetic heat cycle is considered by allowing heat conduction in the inner pipe wall of the device. According to the heat transport configuration studied, the lower end of the device is heated while the upper end is cooled isothermally when the device is placed vertically. Experimental results show that a relatively high amount of heat can be transported in comparison with the case of an adiabatic inner pipe wall, indicating that the thermomagnetic heat cycle in the device is improved. The correlation obtained from one-dimensional analysis provides a reasonable means of assessing estimating experimental data when the thermomagnetic heat cycle based on the working principle is satisfied.

A numerical analysis is conducted in order to study the flow state and thermal characteristics of a magnetic fluid heat transport device. A simple geometrical model of the device is considered in the present numerical study. The highly simplified marker-and-cell (HSMAC) method is adopted for the numerical analysis, where the transient solutions are obtained in the two-dimensional axisymmetric computational plane. From results of the numerical calculation it can be shown that the vortex zone appears when a magnetic field is applied and the configuration of flow associated with the vortex zone changes for variation in the magnetic field, increasing or decreasing the heat transport capability dependent upon the conditions of the device.
