“…Gao et al − conducted detailed experiments to figure out the composition of the pressure drop. You et al reported that the maximum tangential velocity was located at the inlet section, which was around 1.2 times larger than the inlet gas velocity based on the simulation results. Liu et al , discussed the effects of the dust cake on fine dust collection efficiency in the coupled separator and defined critical porosity to identify the transition from the cake filtration to the deep-bed filtration.…”

The gas–solid separator of coupling cyclone with a built-in granular bed filter (GBF) was proposed to capture dust emitted from the industrial source. The coarse dust was separated by the rotatory motion, and the fine dust entrained by the swirl was collected by the GBF. A new geometrical parameter, named as the swirl space ratio, was introduced to characterize the mutual impacts on the coupled separator. Experimental results showed that the pressure drop decreased 10% when the swirl space ratio increased from 0.37 to 0.43, while the collection efficiency was enhanced significantly. The coupled separator with a large swirl space ratio exhibited excellent separation characteristics according to the separation quality factor. Furthermore, the contribution ratio of the cyclone shell was strengthened by increasing the swirl space ratio. The variation in the bed voidage and the pressure drop was completely opposite. The breakage phenomenon was observed in the circulation of the collector particles.

“…Using the differences in physical and chemical properties of each component in the mixture, the process of distributing each component to different spatial regions is called separation. Typical applications include the cyclone separator [50][51][52][53], hydrocyclone [54,55], classifier [56][57][58], filter [59][60][61][62] and dust collector [63,64]. In the separation process, CFD-DPM is used to obtain the fluid and particle behavior in the internal space, so as to further study the separation performance [65][66][67].…”

Complex fluid–solid systems generally exist in process engineering. The cognition of complex flow systems depends on numerical and experimental methods. The computational fluid dynamics–discrete phase method simulation based on coarsening technology has potential application prospects in industrial-scale equipment. This review outlines the computational fluid dynamics–discrete phase method and its application in several typical types of process engineering. In the process research, more attention is paid to the dense condition and multiphase flow. Furthermore, the CFD-DPM and its extension method for comprehensive hydrodynamics modeling are introduced. Subsequently, the current challenges and future trends of the computational fluid dynamics–discrete phase method are proposed.
