Abstract
- The paper deals with an investigation of velocity field in a tank stirred by a standard Rushton impeller located in the middle of the tank height. Time-resolved PIV method was used to measure the angle-resolved velocity field near the impeller blades in horizontal and vertical planes as well. Based on a simplified criterion λ 2 < 0 the location, size and strength of trailing vortices behind the blades were determined. The measurements were carried out in two tanks of diameters T = 0.3 and 0.4 m and at mixing Reynolds numbers in a range 3.3–4.9 × 10 4 . Simultaneously a detached eddy simulation (DES) was performed for the tank diameter T = 0.3 m and rotation speed 200 rpm ( Re M = 3.3 × 10 4 ). The simulation results are compared with the experimental data. [ABSTRACT FROM AUTHOR]
