EFFECT OF DILUTE SOLID PHASE ON THE MAGNITUDE OF ACCELERATION TERM OF TOTAL PRESSURE DROP IN HORIZONTAL GAS PIPES

Abstract

In this study, the effect of dilute solid phase on the magnitude of acceleration term of total pressure drop in horizontal gas pipes is investigated. The percentage contribution of pressure drop due to acceleration to the total pressure drop was studied at different pipe diameters, pipe lengths, solid concentrations, and solid-gas density ratios, respectively. The results showed that the contribution of pressure drop due to acceleration to the total pressure drop for gas-solid systems could generally be considered insignificant (less than 1%).
