Pressure Drop in Horizontal Taper Pipe of Dense-Phase Pneumatic Conveying

Abstract:

Experimental research was performed to describe the pressure drop occurring in horizontal taper pipe of dense phase pneumatic conveying, which were widely used in the engineering project. Compressed air was used as transmission power and fly ash as the transport medium. Results showed that the geometric parameters of taper pipe including taper angle and diameter ratio had a dominant effect on the pressure drop of the gas solid flow. In addition, a three-dimensional numerical simulation was performed to show the trend of the pressure field intuitively in the transporting process. And the simulation results of pressure drop were validated by the experimental data.
