Abstract

Based on the publications in aspacts of thermodynamics

kinetics

as well as hydrodynamics

many modeling methods by advanced computer technology were analyzed and the numerical simulation of polymer membranes phase separation process were evaluated in this paper. From simple binary systems to complicated ternary and quternary systems

isothermal to non-isothermal mass transfer

application of self diffusion coefficients to mutual diffusion coefficients

one-dimention diffusion to2D or3D

the results from Monte Carlo

Lattice Boltzmann method

Cahn-Hilliard equation

material and energy equilibrium

dissipative particle dynamics and so on were investigated and analyzed. Dominated by different mechanism

several kind of mass and heat transfer phase separation models were detailed discussed

and important disadvantages were dedicated. The developments of phase separation numerical models were finally prospected from theoretical investigation to prectical application.
