Heat Transport and Driving Force Characteristics of Heat Transport Device Using Magnetic Fluid in Various Magnetic Fields

Abstract

In order to evaluate the heat transport capability in the thermomagnetic cycle using temperature sensitive magnetic fluids, a fundamental design work is conducted for practical applications. In the present study, the heat transport characteristics together with pressure characteristics are examined for various magnetic field configurations by means of a numerical analysis and experiments. It is found that the distribution of magnetic field in the radial direction of an electromagnet largely affects the force and the heat transport characteristics. From results, it is shown that the aspect ratio of an electromagnet is the key factor.
