Pickup – Following on the original work of Rizk on saltation Cabrejos and Klinzing (1994) worked in order to determine if there was a broader scope of pick-up and saltation expressions that could be used for a wide cadre of materials. Some interesting results emerged in these studies to show a hysteresis seen between the two phenomena and how difficult
determining the exact values for fine particle behaviors could be. Kalman (2008) and his students have explored even further into these phenomena and have developed new generalized correlations for us all to use. Figure 11 shows the Cabrejos experimental findings.
