Numerical modeling of internal flows in tanks with baffles

The proposed article presents the materials of experimental and mathematical studies internal inertial flows an incompressible liquid during its fluctuations in tanks. An analysis modern problems related to harmful effect resonant splashing on tank structures, as well trajectory nature object movement itself with liquid, was carried out. use damping baffles guide devices similar closed allows fundamentally change structure flows, reducing gradients shock pressures redistributing main effects. Numerical modeling such qualitatively confirms results us build a rather complex three-dimensional development picture fluid flows. In addition it is make plane perforated different degrees permeability due diameter holes their number. hydraulic resistance occurs when flow energy lost overcoming artificial obstacles form small diameter. Thus, effects walls are predicted have smaller amplitude duration. dampers labyrinth structures control force only by means thus reduce number dimensions devices.
