摘要
颗粒流体两相流能量最小多尺度作用模型(EMMS模型)认为,不均匀两相流系统中存在多尺度的相互作用,通常的动量质量守恒条件并不足以确定系统的状态,稳定性条件是必要的。该模型实现了对不均匀两相流状态的定量描述和对聚式散式流态化系统的统一关联,并揭示了不均匀结构、饱和夹带、流型过渡等重要现象的机理。本文简述了该模型的基本思想和要点。
The energy-minimized multi-scale(EMMS)model processes that there exist more than one scale of interaction between fluid and particles in heterogeneous two-phase flow, and that the conventional mass and momentum conservation conditions are not sufficient for determining the hydrodynamic states of a system without an additional condition on system stability, with such a consideration, fluid-particle two phase flow is simulated,yielding an exposition on the heterogeneous flow structure, saturation carrying capacity, regime transition and so on
