Pressure Drop of Y-Shaped Branch Pipe in Gas-Solids Flow
This work concentrated on being able to predict the resistance properties of Y-shaped branch pipe in gas-solid two phase flow. Y-shaped branch pipeline with one branch angle keeping constant and the other being changeable experimental system was built up. Micro-glass bead and millet with similar particle diameter and different solid density were conveyed in the experimental system. As a result, trends of pressure drop on each branch pipe were expressed to perform resistance properties. It can be concluded that pressure drop of the two materials had similar trend and was significantly affected by the branch angle and gas velocity. Meanwhile, the deposition velocity was defined in this study. The relationship between the solids loading ratio and pressure drop on each branch pipe was given based on experimental data, which agreed the theoretical analysis well.
