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/m
³
and 2510 kg/m
³
, average particle diameter 2 mm were carried out at horizontal Y-shaped branch pipe which were designed with one branch being unchanged (keeping 15deg) and the other being changeable (the angle values are 5deg, 10deg, 15deg, 20deg, 25deg, 30deg 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.
