Hard-sphere Fluid: Structure and Viscosities
- 14 Downloads
As it was demonstrated earlier the mode-coupling approach taking into account the interaction between shear dynamic modes and soft density fluctuations gives the expression for shear viscosity which is in a good agreement with the viscosity of various liquids at low temperatures. The aim of this paper is the more careful study of corresponding relations for shear and bulk viscosities of hard-sphere fluid. The hard-sphere fluid is the simplest non-trivial example of the system having liquid-solid transition. It can be studied by molecular dynamics which allows to calculate accurately all the necessary parameters. It is demonstrated that the modecoupling expressions for viscosities agree well with the simulation results.
