Studying the process of the polyethylene granules pneumatic transportation in the pipeline rotary bends

Pneumatic transportation of the polyethylene granules is widely used in the chemical industry due to a number of advantages. They include high productivity, ecological friendliness, ease in installation, and automated process control. The paper presents results of mathematical simulation of a two-phase flow (gas and granules) using the Euler-Euler and Euler-Lagrange approaches, as well as of the dense discrete phase model. It provides recommendations in selecting a mathematical model and refining its parameters to describe the process of the polyethylene granules pneumatic transportation. Mathematical model of the Euler-Euler working process is verified by comparing it with the experimental data. The discrepancy is not exceeding 5%. The two-phase flow Euler-Euler mathematical model makes it possible to study the influence of various factors on main characteristics of the polyethylene granules pneumatic transportation system.
