WitrynaIn general, axial-flow impellers have blades which make an angle of less than 90° to the plane of rotation and promote axial top-to-bottom motion. Propellers are axial-flow devices, as are pitched-blade turbines such as that shown in Figure 7.19. The flow pattern set up by a typical axial-flow impeller is illustrated in Figure 7.20.

Witrynatype and also either curved or flat blade type. Radial flow impeller without disc does not produce mixing in a proper radial direction since pressure gradient occurs on either side of the rotating impellers. Radial impellers with disk have higher power consumption and gave uniform radial flow patterns. Fig. 1 Radial flow impellers IV. Witrynaimpeller in terms of the flow pattern induced by the agitation. In addition, the present work aims to determine the effect of rotation mode (co- rotation and counter -rotation) on the fluid flow of an aerated yield-pseudoplastic xanthan gum solution (1 wt%) upon varying the central impeller speed and anchor speed.
