The flow field in agitated tank with Disc Turbine(DT) and Pitched Turbine Upflow (PTU) was experimentally stdudied by two dimensional Laser Anemometer. The distribution of velocity from different structure parameters and rotational speed were obtained. Dimensionless velocity of DT was not dependent on the rotational speed, and only varied with the position. Its radial velocity was stronger in the discharge region, nearby the axis and wall. Two vortexes were found in PTU. The bigger one was near the outside ...
