| Outline of Final Research Achievements |
Magnetic fluid is a colloidal dispersion which is composed of surfactant-coated nano-order particles and carrier liquid. Because the inner particles form chain-like structure by applying magnetic field, it can be expected the physical properties vary from time to time and have anisotropy. In this study, thermal diffusivity and rheological property of the magnetic fluid were attempted to measure by forced Rayleigh scattering method (FRSM) and using ultrasonic velocity profiler (UVP), respectively. Regarding thermal diffusivity, time series variation of the thermal diffusivity of magnetic fluid was successfully measured by FRSM and characteristic configuration was obtained. On the other hand, measurement of rheological property of magnetic fluid was not succeeded because of the problem of experimental system. However, characteristic streamwise variation of turbulent structure of turbulent magnetic fluid flow by applying magnetic field was successfully obtained by UVP measurement.
