The pressure drop predictions across a bypass pipeline in dense phase pneumatic conveying were investigated numerically. The simulation was conducted using the commercial Computational Fluid Dynamic (CFD) software Fluent with the Euler- Euler model accounting for four-way coupling. Experiments and calculations were conducted using flyash powder conveyed in a horizontal pipeline. The influence of the pipe length on pressure drop prediction was also investigated. The results indicate that pressure prediction of the CFD simulation model for a bypass pipe is promising. The conclusion is that this investigation can offer improved insight and initial design modelling capability for bypass pneumatic conveying systems.

In the dense phase pneumatic conveying lab table, used horizontal shrinked pipeline as transmission pipe. Used compressed air as conveying power and dry gypsum powder as transported materials, then conducted with gas-solid conveying experiment. Through the experiment, resulted show change law and influence factors of pressure drop in horizontal shrinked pipeline under different transportation conditions.In this study. The results showed that diameter ratio, solid and gas mass ratio and diffusion angle could affect the pressure drop of the pipeline .

Taper Angle

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.
