| Research Abstract |
In this study, our aim is to develop high-performance industrial machines utilizing "Intelligent" and "Functional" fluids such as magnetic fluids. For this aim, we have performed basic and applied studies on measurement devices using the magnetic fluid, a novel system for energy conversion and transportation and a flow rate control system using "magnetic-elastomer". The devices for measuring of void fraction, bubble velocity and flow regimes of gas-liquid two-phase flow can be achieved by adding a quite small amount of the magnetic fluid to liquid phase. The energy transportation system using a mixture of "magnetic fluid"and "low-boiling-point liquid" can achieve self-circulation of the heat in both horizontal and vertical direction. The MHD (Magnetic Hydro Dynamics) electric power generation device which utilize "electric conductive polymer" has a characteristic that conductivity rises with a rise of the fluid temperature. The output value of voltage by the experiment shows a good agreement to the theoretical value. The flow rate control system using magnetic elastomer is found to be able to control the flow rate effectively by controlling the magnetic field.
