Abstract

The proposed article presents the materials of experimental and mathematical studies of internal inertial flows of an incompressible liquid during its fluctuations in tanks. An analysis of modern problems related to the harmful effect of liquid resonant splashing on tank structures, as well as on the trajectory and nature of the object movement itself with the liquid, was carried out.

The use of damping baffles and guide devices in similar closed flows allows to fundamentally change the structure of internal flows, reducing gradients of shock pressures in flows, as well as redistributing the main liquid inertial effects. Numerical modeling of such flows qualitatively confirms the results of experimental studies and allows us to build a rather complex three-dimensional development picture of fluctuations in fluid flows.

In addition to the use of the damping baffles structures, it is proposed to make the plane of baffles perforated with different degrees of permeability due to the diameter of the holes and their number. The effect of hydraulic resistance occurs when flow energy is lost due to overcoming artificial obstacles in the form of holes of small diameter. Thus, the shock effects of the flow on the walls of the tank are predicted to have a smaller amplitude and duration.

The use of the proposed dampers labyrinth structures allows to control the force effects of the liquid only by hydraulic means and thus reduce the number and dimensions of the internal guide devices.
