A basic study on a newly designed direct-heat-to-power energy conversion device, using a temperature sensitive magnetic fluid, was conducted in order to obtain the fundamental characteristic of the optimized device. The working principle of the device is based on the thermo-magnetic effect of magnetic fluid, in which the driving force (the driving pressure) needed to circulate magnetic fluid in the thermodynamical power cycle can be derived from the magnetization difference in a temperature field. The numerical study used to obtain the basic characteristics of the device is also presented for a cell subjected to the imposed magnetic field and temperature field.
