摘要:
We will present a numerical study of Jeffery orbits with Navier slip boundary condition applied at anisotropic solid particle’s surface in shear flow. The Fluid Particle Dynamics Method (developed by Tanaka and Araki) was employed. The effects of surface slip on Jeffery orbits were quantitatively demonstrated. Due to the presence of cross coupling between translational and rotational degrees of freedom, theoretical analysis was carried out for the hydrodynamic reciprocal relations of Lorentz and Onsager. These results are related to active matter that can be modeled as active nematic liquid crystal.
