Abstract: The flow and thermal characteristics in a parallel duct-type energy conversion device utilizing a magnetic fluid under a nonuniform magnetic field were analysed using theoretical equations from heat conduction suggesting a laminar developing flow. The theoretical results regarding pressure difference and temperature distribution were compared with experimental results. The present heat conduction model is capable of explaining the experimental data both quantitatively and qualitatively. Coincidence was found to be independent of the performance of the applied magnetic field, which is an important factor in an energy conversion device.
