Abstract
We propose a numerical model of the dynamics of phase separation in polymer mixtures based upon the generalized two-fluid model developed by Doi and Onuki [J. Phys. (France) II 2, 1631 (1992)] using the method of smoothed-particle hydrodynamics. Our model is applicable to rheological studies of the phase-separating systems. We present our simulation results on the kinetics of domain growth and the phase separation under simple shear flow in two dimensions. We also discuss how the viscoelastic effect is incorporated into our model.Keywords
