AB - A new theoretical model for predicting particle separation efficiency in bends is developed
based on the investigation of flow pattern, the critical particle size separation theory and the boundary
layer separation theory. The radial particle concentration gradient, instead of the usually assumed
uniform radial particle concentration within the bends, is considered in this mathematical model. The
local particle concentration and the separation efficiency can be calculated on the base of a
time-of-flight model in terms of the particle size distribution of the feed. The effects of curvature ratio
and bend angle on the separation efficiency in bends are also evaluated by the model.
