Notes:
Two-phase solids-in-air flow was experimentally studied in a once through flexible wall tube flow system using nominal 25μm and 50μm spherical glass beads. For turbulent flow through the Silastic tube without a damping medium behind the wall, cases of true drag reduction and no drag reduction were found. The rate of addition of the glass beads was seen to be a correlatable parameter for both the flexible and rigid wall systems. A mechanistic model is proposed for interpretation of the results. It was qualitatively observed that the presence of an electrostatic charge on the particles at low relative humidities had a pronounced effect on increasing the drag in the system.
