Flow distribution property of Y-Shaped branch pipe in gas-solid two-phase flow

The flow distribution property of gas-solid two-phase in Y-Shaped branch pipe was expatiated. The pneumatic conveying experiments for millet and micro-glass bead with density 1340 kg/m3 and 2510kg/m3, average particle diameter 2mm were carried out at horizontal Y-shaped branch pipe which were designed with one branch being unchanged (keeping 15°) and the other being changeable (the angle values are 5°, 10°, 15°, 20°, 25°, 30° respectively ). The flow distribution property was expressed by the ratio of the solid mass flowing in the changeable branch vs. the total mass of solid.
