Abstract:
The method of theoretical analysis and numerical simulation is used to study the velocity distribution and pressure drop of gas-solid two-phase flow in a vertical pipe. Based on the Euler model and the particle dynamics theory, a mathematical model suitable for the dense phase gas transportation process of petroleum coke was established. The model considers the collision and friction of petroleum coke particles, while also considering the friction between the particles and the tube wall, analysis of superficial gas velocity, particle diameter and the influence of petroleum coke particle mass flow rate in a horizontal pipe gas-solid two-phase velocity, concentration and distribution of pressure drop.
