Dmitrienko D. Increasing of industrial pipeline transport of slurries efficiency by fluidic fittings application.

А solution of scientific task of increasing the efficiency of equipment and processes of the industrial pipeline hydraulic transport is presented. Possibility of VRO work on slurries is first proven by experimental and theoretical researches. The scopes of VRO ability to work are set, they depend on granulate, fractious composition and concentration of solid phase of slurry, but does not limit a flow capacity and transport-technological systems of these devices application. First numeral calculations and experimental researches are set the features of flow of slurry in VRO. Unlike a clean environment, slurry flow in VRO hasn't Coanda effect, even without establishment of stabilizer has symmetric character that allows simplification of flow part configuration and increases a carrying capacity. Theoretical researches and mathematical models of flow in the work chambers of VRO at presence of solid phase got further development. Kinematics descriptions of motion of the isolated particles are set, criteriawhich govern trajectories and character of their motion are defined. First hydraulic characteristics of VRO work on slurries are set in experimental way. The features of joint work of VRO with hydraulic transport equipment are first defined by theoretical and experimental researches.
