Phase Separation

To simulate multiphase fluids, we need long range interactions between fluid ‘particles’. Shan-Chen Model For our purposes interactions with nearest neighbor particle densities f will be sufficient to simulate the basic phenomena of multiphase fluid interactions. For single component multiphase fluids (e.g., water/water vapor) an attractive (cohesive) force F between nearest neighbor fluid particles is needed and, for the D2Q9 model, is induced as follows: $$ \boldsymbol{F}(\boldsymbol{x},t)=-G\Psi(\boldsymbol{x},t)\sum_{a=1}^{8}w_a\psi(\boldsymbol{x+e_a}\Delta t,t)\boldsymbol{e_a} $$ where G is the interaction strength, wa is 1/9 for a={1, 2, 3, 4}, is 1/36 for a={5, 6, 7, 8}, and psi (Greek letter) is the interaction potential: ...
