Abstract: Laser Dopplcr vclocimcter measurements of gas-particle flows are made in a curved duct with strong curvature. The velocity distribution of the solid phase on each cross-section of the duct is flat, but is lower than that of the gas vclocity.It is observed that- the solid phase has remarkable influences on the tangential and radial velocities of the gas phase.

Key words: two-phase flow, duct flow, laser measurement
