Porovnání měřených okamžitých rychlostí a modelovaného proudění v míchané nádobě

Original language description

Mixing process is driven by changes of the velocity flow field and creation of the vortices structures during the operating time. In this study we compare the CFD (Computational Fluid Dynamics) calculations with experimental results of mean ensemble-averaged velocities and also the angle resolved experimental results of velocities which depend on the impeller movement that generate the vortices. The experimental data of temporal series of 2D vector maps of the velocities were obtained from the time resolved PIV measurements in the impeller region. For the instantaneous velocities and the investigation of the vortices in the impeller vicinity the LES (Large Eddy Simulation) were employed with combination of SM (Sliding Mesh) modelling of the impeller movement. The application of method and results are discussed and compared.
