Frequency Analysis of the Wake Behind a Baffle in the PBT Mixing Vessel
Original language description
This article is devoted to an experimental investigation of the flow field behind a radial baffles located in a mixing vessel equipped with a pitched blade turbine (PBT) impeller pumping downward. The dynamics of the flow is studied using time-resolved Particle Image Velocimetry (PIV) anemometry method and the various modes are detected using Oscillation Pattern Decomposition (OPD) method. Through OPD analysis, the quasiperiodical structures are revealed and highlighted in the flow structures of the vortex wake. This research explores frequencies which did not exceed blade passage frequency (BPF). Such results can be very helpful to validate CFD models and to design vessels with better efficiency of mixing process.
