Abstract
The magnetic body force in boiling a two-phase temperature-sensitive magnetic fluid (TSMF) flow is known to effectively increase the driving force of magnetic fluid in a non-uniform magnetic field. Based on this mechanism, in the present study, a binary TSMF, which is a mixture of the TSMF and a low-boiling-saturation-temperature organic solution, is proposed to be used in a heat transport device to enhance its circulation. In order to see its performance in the heat transport device, the pressure difference at different heated temperatures and magnetic fields is investigated experimentally and theoretically when the heating section (test section) positioned horizontally. Results showed that the pressure difference (driving force) increases with both the increase of the axial maximum magnetic field intensity and that of the heated temperature. This was the results of the temperature-dependent magnetization of TSMF and the decrease of the magnetization due to the gas bubble occurrence in the heating region.
