Outline of Final Research Achievements

A magnetocaloric fluid (MCF) is a kind of metal particulate slurry which induces both the heat generation and absorption with a magnetocaloric effect. Because the MCF has a superior fluidity and functionality as a unique thermo-functional fluid, the development of state-of-the-art thermal devices using the MCF is expected in the future. The purpose of this study is to evaluate the fundamental characteristics of MCF as well as the composing a cooling/heating device with the MCF. Gadolinium and lanthanum compound particles are selected as the dispersed phase. And a carboxymethylcellulose solution is adopted as the continuous phase for the MCF. As the result of research, the following remarkable knowledge is derived: (1) the preparation method of MCF was established; (2) the basic thermal properties were determined; (3) the possibility of the cooling/heating device with the MCF was confirmed.
