Results for transport properties, in conjunction with phase behavior and thermodynamics, are presented to understand the critical behavior of a binary Lennard-Jones fluid, on the basis of Monte Carlo and molecular dynamics simulations. Evidence for much stronger finite-size effects in dynamics compared to statics has been demonstrated. Results for bulk viscosity are the first in the literature where the critical divergence is quantified via a novel application of finite-size scaling. Our results are in accordance with the theoretical predictions of mode-coupling and dynamic renormalization group calculations.
