In this study, our aim is to create high-performance industrial machines utilizing “Intelligent” and “Functional” fluids such as magnetic fluids. For this aim, we have done basic and applied studies : measurement devices for multi-phase flow using electromagnetic induction method, a novel MHD device and natural convection of magnetic fluids in porous media. In the research of measurement for multi-phase flow, the measurement of not only void fraction and bubble velocity but also concentarion of solid-phase and volume of solid particle could be achieved. In the study of MHD power generator, the present generator demonstrates the maximum output electric power of 3.6 mW by changing in width of flow channel. In the study of natural convection in porous media, the experimental and numerical results show that heat transfer characteristic of the magnetic fluid is enhanced when the magnetic field is applied to the magnetic fluid.
