複雑流体のレオロジー計測−新しい測定法あれこれ−

抄録

The dynamic aspect of the Brownian motion and the viscosity, as well as the thermal conduction, is described as the process of diffusion, of which temporal evolution is characterized by a diffusion constant. In this article, we introduce our recent studies on the field of rheology. One is the measurement of the local rheology in the vicinity of the solid boundary through the observation of the dynamic light scattering with the evanescent light source, and the other is the development of the Elecro-Magnetically Spinning (EMS) viscometer. In the former, we show the evidence of the anisotropic Brownian motion near the solid wall, and in the the latter, an idea for the ultra high viscosity measurement is also proposed.
