An Experimental Study of Swirling Flow Pneumatic

conveying velocity, pipe wear, and particle degradation. An experimental study has Yuji Tomita addressed the characteristics of swirling flow pneumatic conveying (SFPC) for the Professor, total pressure drop, solid flow patterns, power consumption, and additional pressure Department of Mechanical Engineering, drop. Polystyrene, polyethylene, and polyvinyl particles with mean diameters of 1.7, Kyushu Institute of Technology, 3.1, and 4.3 mm, respectively, were transported as test particles in a vertical pipeline 1-1 Sensuicho, Tobata, Kitakyushu, 12.2 m in height with an inside diameter of 80 mm. The initial swirl number was Japan varied from 0.38 to 0.94, the mean air velocity was varied from 9 to 23 m/s, and the
