RHEOLOGICAL CHARACTERISTICS OF SUSPENSION FLOW AND THEIR INFLUENCE ON THE HYDRAULIC TRANSPORT PROCESS

Abstract

The rheological characteristics of suspension flow play a significant role in determining the efficiency and stability of hydraulic transport systems used in mining, chemical, metallurgical, and construction industries. Suspensions containing solid particles exhibit complex flow behavior that differs considerably from conventional Newtonian fluids due to the interaction between solid and liquid phases. This study investigates the rheological properties of suspension flows and analyzes their influence on the hydraulic transport process in pipeline systems. Special attention is given to the effects of particle concentration, particle size, viscosity, and yield stress on flow behavior, pressure losses, and energy consumption. The study examines the transition between laminar and turbulent flow regimes and evaluates how non-Newtonian characteristics affect slurry transportation efficiency. Rheological models, including the Bingham plastic model, are applied to describe suspension behavior under different operating conditions. The research also discusses the impact of rheological parameters on sedimentation, pipeline blockage, and pump performance. In addition, Computational Fluid Dynamics (CFD) methods are considered for analyzing velocity distribution, pressure gradients, and particle movement in hydraulic transport systems. The results indicate that rheological properties strongly influence hydraulic resistance and transport stability. Proper evaluation of suspension rheology is essential for optimizing pipeline operation, reducing energy losses, and improving the reliability of hydraulic transport processes.
