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.

Pool Boiling Heat Transfer

In this paper, the performance of pool boiling heat transfer using a binary temperature sensitive magnetic fluid in the presence of a non-uniform magnetic field is investigated numerically. By using a binary magnetic fluid, enhanced boiling heat transfer is obtained by thermomagnetic convection without deterioration of properties of the fluid. This work is aimed at gaining a qualitative understanding the magnetic field effects on boiling heat transfer enhancement of magnetic fluids. In order to accomplish this, the boiling process and the effects of position of the external magnetic field on flow pattern and heat transfer are investigated in a 2D rectangular domain using COMSOL Multiphysics simulation software. Finally, the boiling curves for a binary temperature sensitive magnetic fluid and its base fluid (without magnetic particles) are compared for various applied heat flux magnitudes.
