We use molecular dynamics (MD) simulations to study surface-directed spinodal decomposition (SDSD) in unstable binary (AB) fluid mixtures at wetting surfaces. The thickness of the wetting layer R1 grows with time t as a power-law (R1∼tθ). We find that hydrodynamic effects result in a crossover of the growth exponent from θ≃1/3 to θ≃1. We also present results for the layer-wise correlation functions and domain length scales.
