Study of Interaction Between an Axial Particle-Suspended Gas Flow and Radial Gas Jets in a Variable Cross-Section Cylindrical Channel

Resumo

The results of experimental investigations of hydraulic characteristics of an axial particle-suspended gas flow in a cylindrical channel enlarged suddenly upon interaction with radial gas jets are reported. The flow velocity variation along the pneumatic pipe height and the pattern of particle motion in the pneumatic pipe are studied. It is shown that hydraulic resistance to a flow containing solids depends essentially on the radial gas jet velocity and mass solid concentration.
