Shear-induced distortion of intramolecular and intermolecular correlations in liquids: Time-dependent density-functional theory

Shear viscosity of molecular liquids is formulated and calculated with use of a time-dependent density-functional theory. Allowing for nonrigidity of each molecule, we obtain shear-induced distortion of both intramolecular and intermolecular correlations self-consistently, which makes it possible to calculate the shear viscosity. As a by-product we derive and solve a hypernetted-chain closure for equilibrium correlations in deformable molecular liquids. © 1996 The American Physical Society.
