ANALYSIS OF FLOW REGIMES IN THE TRANSPORTATION OF HIGH-CONCENTRATION SLURRIES

The transportation of high-concentration slurries through pipeline systems is widely used in mining, metallurgical, chemical, and construction industries. The hydrodynamic behavior of such mixtures significantly differs from conventional liquids due to the high content of solid particles, increased viscosity, and non-Newtonian flow characteristics. This study analyzes the flow regimes occurring during the transportation of high-concentration slurries, including laminar, transitional, and turbulent flows. Special attention is given to the influence of particle concentration, particle size, flow velocity, and rheological properties on hydraulic resistance and pressure losses in pipelines. The research also examines the conditions leading to particle sedimentation and blockage formation in slurry transport systems. Mathematical models and hydraulic equations used for determining Reynolds number, critical velocity, and head losses are discussed. Furthermore, the role of computational fluid dynamics (CFD) methods in predicting slurry flow behavior and optimizing pipeline operation is highlighted. The results demonstrate that accurate analysis of flow regimes is essential for improving transport efficiency, reducing energy consumption, and increasing the operational reliability of slurry pipeline systems.
