In order to further analyze the flow pattern in the impeller area, the impeller inlet section 1–1 and the impeller pressure surface are analyzed. WitrynaA typical liquid circulation pattern set up by a high-speed radial-flow impeller is shown in Figure 8.7. Liquid is driven radially from the impeller towards the walls of the tank where it divides into two streams, one flowing up to the top of the tank and the other flowing down to the bottom. optical angle sensor

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. 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.
