A Theory on the Operation of a Single-Tube Pneumatic Conveyor

Abstract

A refined physicomathematical model based on interacting mutually penetrating continua is proposed for a pneumatic conveyor to transport granular materials under the transitional and the unsteady state. In this model, the pneumatic conveyor is considered a system of mutually influencing equipment interrelated via the laws of mechanics. The proposed model of a pumping pneumatic conveyor may estimate the change of system operation parameters with time, along the transportation duct length, to select the best pneumatic conveying equipment. The suitability of this model is confirmed via experimental studies.
