電場下の粒子分散型電気粘性流体の流体力学特性についての粒子の影響を考慮した理論解析による流体力学的検討 Hydoronamic Investigation on Hydrodynamic Characterristics of Electrorheological Fluid of Particles Dispersion Type in an Electric Field Taking into Account the Effect of Particles
Theoretical investigation was made on the hydrodynamic characteristics taking into account the effect of the particles of electrorheological fluid (ER fluid) which is a type of colloidal dispersion. First of all, the numerical calculation supposing the uniform dispersion of each sphere particles were made and the results were compared with the experimental data at the case of rotating flow in concentric cylinder as one of the cases of fluid flow. Secondly, the quantitative or qualitative difference between them was investigated under the assumption that the cause of the difference is aggregation of the particles, and the difference was estimated with using the equation of the increment of viscosity by applying an electric field taking into account the aggregation.
