Investigation on the evolution of flow field stability in a spiral …
The emerging smoothed particle hydrodynamics (SPH) model was proposed to simulate the multiphase flow in a Humphrey spiral separator (Kwon et al., 2017). Moreover, computational fluid dynamics (CFD) methods are relatively mature and have often been used to understand the separation process in spiral separators.

Principles of spiral concentration
An improved mathematical model to simulate the particle and flow behavior in a coal-washing spiral has been developed. The modeling framework addresses three main components of the spiral system: (i) geometry of the spiral and its trough, (ii) fluid motion along the curvilinear path of the spiral and (iii) principal forces acting on a particle incorporating "Bagnold …
