Abstract
Expressions for the wave number dependent shear viscosity and longitud inal viscosity are obtained using generalized hydrodynamics and Mori f ormalism. The results obtained for shear viscosity and longitudinal vi scosity have been used to calculate the wave number dependent bulk vis cosity for the Lennard-Jones potential near its triple point. It has b een found that the bulk viscosity becomes negative for wave numbers gr eater than 0.8 angstrom-1.
