Abstract

After reviewing existing theories in detail, the author has found a serious error in a popular model for the prediction of pressure drop in single-slug dense-phase pneumatic flow. The purpose of this study is to analyse the mechanism of slug flow and develop a new method for determining pressure drop accurately, so that commercially used densephase pneumatic conveying systems can be designed by theory. The present study lays the foundation for modem dense-phase pneumatic conveying design. Subsequent investigators and prospective users of the system will benefit from this work mainly in three aspects: (1) a better knowledge about the conveying mechanism; (2) a more accurate estimation of the operating factors; (3) a design based more on theory than empiricism.
