| Description
| - Jsou studovány chaotické aspekty makro-nestabilitních komponent toku kapaliny v míchacích nádobách. Experimentální data pocházejí z cylindrických míchacích nádob s plochým dnem promíchávaných buďto lopatkovým nebo turbinovým míchadlem. Jsou použita data různé fyzikální podstaty ? rychlostní data a síly působící na narážky. Jsou rekonstruovány chaotické atraktory makro-nestabilitních složek dat a určeny hodnoty jejich chaotických invariantů v závislosti na geometrických a provozních parametrech míchací nádoby. (cs)
- Chaotic features of the macro-instability (MI) of flow patterns in stirred tanks are studied in this paper. Datasets obtained by measuring the axial component of the fluid velocity and the tangential force affecting the baffles are used. Two geometrically identical, flatbottomed cylindrical mixing tanks (diameter of 0.3 m) stirred with either pitched blade turbine impellers or Rushton turbine impeller are used in the experiments, and water and aqueous glycerol solutions are used as the working liquids. First, the presence of the MI component in the data is examined by spectral analysis. Then, the MI components are identified in the data using the proper orthogonal decomposition (POD) technique. The attractors of the macro-instability are reconstructed using either the POD eigenmodes or a method of delays and finally the attractor invariants are evaluated. The dependence of the correlation dimension and maximum Lyapunov exponent on the vessel operational conditions is determined together with their dis
