17.5.5. Interfacial Area Concentration Interfacial area concentration is defined as the interfacial area between two phases per unit mixture volume. This is an important parameter for predicting mass, momentum and energy transfers through the interface between the phases. When using the Eulerian multiphase modelwith non-granular secondary phases, you can have ANSYS Fluent compute the interfacial area in one of two ways: use a transport equation for interfacial area concentration as described in Interfacial Area Concentration. This allows for a distribution of bubble diameters and coalescence/breakage effects. use an algebraic relationship between a specified bubble diameter and the interfacial area concentration. 摘选自Fluent help 17.5.5 既然颗粒相的界面比面积不能用现有的两种方法来计算，那该怎么计算呢？  ——对理论理解的越深，越发现自己一开始的想法错的离谱，模拟也越难以为继。  @wuming524 |
