Engineering Model of Dilute Pneumatic Conveying
Publication: Journal of Engineering Mechanics
Volume 130, Issue 7
Abstract
We introduce a simple model of gas–particle flow in a pipeline, which can be used as a tool in engineering design. A chaotic particle motion due to the particle–particle and particle–wall collisions is modeled by analogy with the motion of gas molecules. The pressure gradient is calculated as a sum of particles drag forces per unit volume. As a result, the problem of pressure losses is reduced to the solution of one nonlinear algebraic equation. The gas viscous friction losses are found by the Colebrook–White approximation. The model is validated by testing it against the experimental data and other, more sophisticated, models known in the literature.
