1 Axial Velocity2 Turbulent Intensity3 Pressure Drop4 Collection EfficiencyThe axial velocity and gravitational acceleration in a cyclone are responsible for transporting solid particles. The axial velocity consists of the downstream gas-particle flow in the outer vortex region and the upstream gas–solid flow in the inner region. Upstream gas–solid flow may include some particles. Figure 6illustrates the paths of the part...
