Abstract
AbstractWe present the results of a computer simulation of the dynamics of a hard sphere suspension without hydrodynamic interactions that was performed using an algorithm recently developed by the authors. The dynamical structure factors and the mean‐square displacement have been calculated for various volume fractions between 0.1 and 0.5. Is is shown that the temporal behaviour of the time derivative of the mean‐square displacement is very well described by the stretched exponential function exp(‐const.√t). It is also shown that the results for the dynamical structure factors almost perfectly agree with those of a theory combining in the proper way the Enskog term with the mode‐mode coupling term.
