| 摘 要： | 从颗粒的全受力分析、气固两相流系统能量的趋于稳定法则及直接从当量直径折算这3种方法着手，经理论推导，得到了稠密气固两相流中颗粒密集效应的定量表达式，并采用得到的3种计算模型，研究了一典型的两相流场中颗粒密集效应的大小，研究结果表明，该模型是合理的，能定量揭示颗粒密集效应的大小。

| Abstract: | The magnitude of particle clustering impact for dense gas-particle two-phase flow is theoretically studied. Three calculation expressions are deduced based on the force analysis, the principle of minimal potential energy, and the equivalent-diameter converting methods. Reasonable results of the particle clustering impact in a two-phase flow field are obtained by using these three models.It shows that these models are feasible and can be used to study the particle clustering impact efficiently. |
