| 摘 要： | 原多组分Shan-Chen模型在模拟气液流动时受到密度比的限制，经过测试，该模型在模拟气液流动时最大密度比为50左右。本文提出了利用改进后的多组分Shan-Chen模型模拟密度比为175的两液滴相溶，模拟结果与实验结果相符。 |

| Abstract: | The original multicomponent Shan-Chen model suffer from the density ratio problem, which can roughly reach a highest density ratio of 50. In this paper, we simulate the process of coalescence of two droplets with density ratio of 175 based on improved multicomponent Shan-Chen model. The simulation results conform to the experiment results. |
| Keywords: | multicomponent multiphase flows large density ratio Shan-Chen model Lattice Boltzamnn Method. |
