Abstract

<p> Nanofluids have attracted much attention in the field of heat transfer because of their exceptional heat transfer ability. The authors have proposed a silver nanowire-dispersed magnetic nanofluid. Interestingly, its thermal conductivity is tunable by the direction of the applied magnetic field, because the dispersed Ag nanowires orient to the field direction. But the dynamic behavior of Ag nanowires is not well understood. In the present study, the translation process of the neighboring two Ag nanowires was theoretically analyzed. When the Ag nanowires are dispersed in the magnetic fluid and exposed to the magnetic field, the Ag nanowires apparently behave as a diamagnetic material because the surface of the Ag nanowires is magnetically charged. With assuming that single magnetic moment places at the center of Ag nanowires, the magnetic dipole interaction force, which is the attraction force, acts on the Ag nanowires, and the wires contact each other with taking a long time.</p>
