The anisotropy of the friction pressure of dipolar fluids
Abstract
The behavior of anisotropic fluids under the influence of a plane Couette flow was investigated. A model fluid where components are parallel dipoles in a strong magnetic field is considered. A simple relaxation assumption for the pair correlation function under shear was used, for the calculation of the linear contribution of the potential part of the friction pressure tensor to shear rate. This assumption is shown to be valid for sufficiently weak dipole moments. The results are consistent with a known assumption for the linear viscosity, that is almost exclusively based on general symmetry considerations. A molecular dynamics program was adapted to the model fluid for the verification of the theoretically predicted relations between the friction pressure components. The simulations are in agreement with theory.
