THE MATHEMATICAL MODEL OF PLUG FLOW CONVEYING

In the paper the movement characteristics of a special plug moving in the pneumatic pipe are described considering forces influencing the plug that acceleration, velocity, and the path made by the plug. The state of motion in horizontal and vertical pipe sections, respectively, in a bend built into the pipe section will be determined. The bend examined in this paper is laying in the vertical plane and is connecting a horizontal pipe section with a vertical one. Equations describing the movement characteristics are approximative because authors simplify the physical process, neglect different things. In the knowledge of the movement characteristics the data of the delivering machine can be determined
