Abstract
The present thesis investigations the hydraulic transport of settling solid-liquid mixture (sand-water) with different grain size, mean velocity and solid concentration in a horizontal pipeline. Thesis summarizes the results of numerical and experimental investigations carried out to describe the flow of sand-water mixtures in pipelines. According to the comparisons between the data from empirical relations with the experimental results a method of a mixture flow prediction can be proposed. An attention has been paid to methods of pressure loss evaluation and specific energy consumption estimation, as power consumption represents substantial part of hydraulic transport cost.
In slurry flow practice, the models used to predict the behavior of mixture flow in pipelines are based on an empirical approach rather than on a physical description. Although the physical approach to the modeling of the pipeline flow of settling mixtures was introduced in two-layer model, it has rarely been used in practice.
