Research on the Pneumatic Conveying of the Sand in the Horizontal Pipe Based on FLUENT

Dan-yang Li, Shu Liu and Xiao-ning Wang

Abstract

The pneumatic conveying experiment bed has been established to study the flow characteristics of air- solids two-phase flow in horizontal pipeline. Euler model was applied to simulate it based on analysis of Gambit and fluid analysis software-fluent. The simulated results indicated: under the same gas phase conveying flow and pressure, the bigger particle diameter is, the bigger pressure drop is in the horizontal pipeline. The smaller particle diameter is, the more uniform of the particle’s distribution is, and the more easily obtaining the acceleration is. Particle concentration at the bottom of the horizontal pipe is increasing in the axial direction, while close to the tail pipe it will be reduce. The simulated conclusion is consistent with the actual measurement results, herewith rendering some footing for engineering design and theoretical research on pneumatic conveying systems.

Funding statement: Funding: All calculations were performed in Liaoning Shihua University. And thanks to the National Natural Science Foundation of China (21276120).
