Size Segregation Studies Using a Primary Segregation Shear Cell

Development and Validation of a Constitutive Model for Size-Segregation during Percolation

“…The precision of µ and δ was held to three decimal places (i.e., 0.000). Equation (11) defines the standard deviation between the actual and predicted data. The term, df, represents the degrees of freedom for the data.…”

“…The values of µ and δ that produced the smallest error were taken as the material parameter for the given set of operating conditions. In Equation (11), M(t i ) represents the experimentally measured mass value at the exit, i.e., corresponding to θ r .…”

“…Percolation is similar to the sieving mechanism (Figure 1) that occurs during shear; however, a moving layer is absent. In the literature, percolation has been studied as a function of gravity and vibration (Tang et al, 2001). Vibration can cause a small individual particle to travel downward through the powder mass.…”
