Abstract

Highly efficient energy-saving methods of pipeline transport have been developed on the basis of modern scientific approaches. A general concept and its implementation on the synergetic basis have been proposed. It is shown that stochastic motion modes arise while passing through intermittence, i.e. they are the result of collision of asymptotically stable and unstable motion states. It has been established that flow of air-fuel mixtures with inner weaves and inner portion turbulent motions is considered as a process of self-organization with collective flows. At the same time, effective coefficients of transfer of momentum, force and mass of the moving material flow are determined. The hypothesis of emergence of stochastic motion modes that arise during transition through intermittency has been justified, which makes it possible to derive the regularity of collision of asymptotically stable and unstable flows of air-fuel mixtures. The rheological model for flow of non-Newtonian fluids is proposed that takes into account the flow features, which makes it possible to determine the shear stress and viscosity of CWF at different values of the shear velocity. The mathematical model takes into account independent rheological parameters of the suspension, which depend on concentration and granulometric composition of coal, as well as on high-speed transportation modes. It has been established that the process of self-organization of mass transfer in the pneumatic transport pipeline is carried out by additional energy supply of the moving material flow and provides creation of additional vorticity of the flow. There have been determined the main tasks solved by intensification of the processes in the transport pipeline, which makes it possible to increase efficiency of its operation.
