Hydrodynamic Seal on the Basis of a Cylindrical Layer of the Compressible Fluid with a Running Wave

The hydrodynamic seal is based on a cylindrical layer of the compressible fluid with a running wave, which, unlike the conventional hydrodynamic seal, has the characteristics that do not depend on the rotation speed of the sealed shaft. The flow of the compressible fluid in the cylindrical gap is concerned, the pressure distribution in the layer are obtained, pressure drops (counterpressure) along the axis of the shaft depending on the gas content in the liquid are determined.
