分区多流域提升管EMMS曳力模型的构建
Development of EMMS-based drag model for multi-regime riser
摘要
Abstract
Considering the phenomenon of gas-solid flow caused by the particle clusters in the circulating fluidized bed (CFB) riser,the energy minimum multi-scale method (EMMS)-based drag model was developed in this study.And the drag model was coupled with the two-phase flow model of CFD for simulations of a conventional riser and a novel multi-regime riser.It is found that the developed drag model can reasonably predict the flow distributions on both axial and radial directions,which leads to the correct characterization of the gas-solid flow in the riser.An appropriate drag models is needed when the configuration and operational conditions in CFB riser are changed.关键词
