Study of the hydrodynamic modes of ejectors for flotation water treatment at space industry enterprises

The paper considers the problem of determining the hydrodynamic modes in the mixing chamber of ejectors with a rectangular mixing chamber by solving the Navier - Stokes equation. The problem is considered for the case of absence of mass forces. To describe the steady-state flows of a viscous fluid in the isothermal approximation, the Navier - Stokes system of equations was used, which includes the continuity equation and the equation for the change in momentum. The solution was obtained using the Maple computer modeling tool. The proposed method adequately describes the process in the mixing chamber of an ejector with rectangular mixing, which potentially indicates the possibility of describing the hydrodynamic modes in the mixing chambers with a different section.
