Abstract This paper demonstrates that our extended smoothed particle hydrodynamics (SPH) model can successfully simulate multiphase flow in a Humphrey spiral concentrator (HSC) with two phases: powder and water. The powder phase in the model was assumed to be a continuum, as the spacing between particles in this state is much smaller than the typical length scale of flow.
This paper investigates the effect of spiral curvature on the flow field within a newly introduced spiral channel viscous micropump. Increasing the spiral curvature increases the angle between the channel axis and the direction of upper plate motion, and more fluid is dragged normal to the axis of the channel, which changes the flow characteristics. A number of 3D models for the pump …
The conventional chromite beneficiation circuit utilises spiral concentrator for recovering chromite fines and as its efficiency decreases with respect to the decrease in particle size. Pilot scale studies have been performed to understand the effect of different process parameters which influence the separation of ultra fine chromite fines from a typical plant tailing.
