Radial And Axial Gas Velocity

Radial gas velocity is the most difficult velocity component to measure experimentally. Figure 5.16.4 shows Kessler and Leith's (1991) measurements of radial velocity profiles in a cyclone. Despite some uncertainty in the measurements, some trends can be seen. Radial flow velocity increases toward the center of the cyclone due to the conservation of mass principle. A tendency also exists for the maximum radial velocity in each cross section to decrease with decreasing cross-sectional height.

Figure 5.16.5 shows the axial gas velocity in a reverse-flow cyclone. The gas flows downward near the cyclone wall and upward near the cyclone axis. The downward velocity near the wall is largely responsible for transporting dust from the cyclone wall to the dust outlet.
