Free liquid surface motions in a stirred tank: an insight into the fluid flow dynamics.
Original language description
In this paper we aim to statistical and dynamical analysis of the free liquid surface motions in two stirred vessels and to investigation of occurrence of local macro-swells of the liquid surface near a baffle. The experiments were carried out in standard flatbottomed cylindrical mixing vessels with four radial wall baffles (inner diameter T = 0.29 m and T = 0.50 m, respectively). Water was used as a working liquid. The liquid level height was equal to the tank diameter. Pitched blade turbines (PBT) ofdiameter D = T/3 with six blades (pitch angle 45o) pumping towards vessel bottom were used for stirring. The impeller off-bottom clearance was C/T = 0.33 in both tanks. The impeller speed, N, was varied from 350 min-1 to 450 min-1 in smaller tank and from 200 min-1 to 400 min-1 in greater one. Corresponding interval of the impeller Reynolds number ReM was 50,000 to 181,500. A rod-shaped conductivity probe was placed at the liquid surface at several locations in a near to the baffle regio
