Molecular dynamical calculations on the transport properties of a square-well fluid: IV. The influence of the well-width on the viscosity and the thermal conductivity

摘要: Abstract The coefficients of the viscosity and thermal conductivity for a system consisting square-well molecules have been determined at constant temperature as function well-width. densities considered in these calculations range from rather low values up to density which is just below fluid-solid phase transition. superposition even narrow attractive well on hard spheres has significant influence viscosity. An also seen kinetic, potential cross terms conductivity, but partially cancel each other. Moreover, short time effects correlation functions found.
