MASS TRANSFER AND BOUNDARY LAYER DETACHMENT UNDER THE AQUEOUS SOLUTION EFFECT ON ROCK SALT
Different variants of the solution's effect on the rock salt surface and the boundary layer, associated with increase of the boundary layer detachment and the mass transfer surface, are considered. Hydrodynamic vortex action of the solution on the surface of rock salt cores forms threedimensional craters with smooth contours, as well as three-dimensional craters with sharp edges. The phenomenon of the salt plate bounding from the salt crystal of the Botuobinskoye deposit (Sakha Republic) in the process of mass transfer under the effect of solution at low temperatures is discovered. The phenomenon of self-organized hydrodynamic vortex structures formation with occurrence of hemispherical crater structures on the rock salt surface of vertical and horizontal models in the process of mass transfer with boundary layer detachment is revealed. The phenomenon of formation of a two-level crater on the surface of a rock salt core has been discovered, when a smaller spiral-shaped crater forms on the surface of a large crater, which deepens into the rock salt. On the surface of a large crater (formed by “large” vortex), the imprint of a small crater is formed under the influence of “smaller” vortex. This phenomenon characterizes the subsequent impact of two different vortices on the salt area with a successive separation of the boundary layer.
