The Structure of Circulating Flows of Viscous in Compressible Fluid near the Radial Inner Baffles

Автори

The results of numerical modeling of axisymmetric flows in tanks with rigid walls, the analysis of the structure and nature of the circulation of the time flow depending on geometrical parameters of partitions and like Reynolds numbers, Euler and Rossby. We found that the circulation flow near the walls can adjust the structure and energy characteristics of the main flow and significantly change the characteristics of the development trends in the area of influence partitions and near its inner edge. In addition, we obtain the data on rational baffles arrangement in the flow in the context of minimizing their weight and number, which is of great importance for the aircraft. The results of numerical and experimental data comparison show the qualitative agreement of results. We establish such characteristics of the flow field as the azimuthal velocity structure of the meridional circulation currents in each case of the flow. We give practical recommendations for design of these internal structures of stabilizing devices.
