摘要：

A numerical analysis is conducted in order to study the flow state and thermal characteristics of a magnetic fluid heat transport device. A simple geometrical model of the device is considered in the present numerical study. The highly simplified marker-and-cell (HSMAC) method is adopted for the numerical analysis, where the transient solutions are obtained in the two-dimensional axisymmetric computational plane. From results of the numerical calculation it can be shown that the vortex zone appears when a magnetic field is applied and the configuration of flow associated with the vortex zone changes for variation in the magnetic field, increasing or decreasing the heat transport capability dependent upon the conditions of the device.
