In this study, particle transport in single-phase and multiphase flows in horizontal pipes is studied. This study includes two main parts: experimental investigation and modeling study. The experimental part of this study includes performing experiments in single-phase and multiphase flows. The effects of different physical parameters such as particle concentration, particle size, particle shape, pipe size and liquid viscosity were investigated in both single-phase and multiphase flows. But, the main focus of the single-phase flow experimental part of this study was on the effect of carrier liquid viscosity on particle transport. In order to achieve this goal, experiments were performed using viscosified water of various viscosity values in both turbulent and laminar flow regimes. In another experimental matrix, particle transport in the presence of oil-water at different water cuts was investigated. This set of experiments enabled us to study the effect of carrier liquid viscosity and density on sand transport in horizontal pipes.

520 $a In this study, particle transport in single-phase and multiphase flows in horizontal pipes is studied. This study includes two main parts: experimental investigation and modeling study. The experimental part of this study includes performing experiments in single-phase and multiphase flows. The effects of different physical parameters such as particle concentration, particle size, particle shape, pipe size and liquid viscosity were investigated in both single-phase and multiphase flows. But, the main focus of the single-phase flow experimental part of this study was on the effect of carrier liquid viscosity on particle transport. In order to achieve this goal, experiments were performed using viscosified water of various viscosity values in both turbulent and laminar flow regimes. In another experimental matrix, particle transport in the presence of oil-water at different water cuts was investigated. This set of experiments enabled us to study the effect of carrier liquid viscosity and density on sand transport in horizontal pipes.
520 $a In the multiphase flow experimental part of this study, experiments were performed to investigate the effect of particle concentration, particle size, particle shape, pipe size and carrier liquid viscosity on particle transport in both intermittent and stratified flow regimes. Following the same trend as the single-phase flow experiments, particle transport was also studied in the presence of oil.
520 $a Besides the experimental side of the project, a new semi-mechanistic model was developed to predict critical velocity in single-phase flow. This model was compared with a large experimental database containing data for both gas-solid and liquid-solid flows. Depending on the definition of critical velocity, the model is able to predict the minimum flow rates that meet critical velocity definitions for both liquid-solid and gas-solid flows. This model was compared with the Oroskar and Turian model and the experimental data available in the Tulsa University Sand Management Projects database, and it was shown that this model can predict critical velocity well for a wide range of operating conditions. The effects of various physical parameters on critical velocity based on the experimental data were compared to the new model predictions, and it was found that this model predicts the effect of these parameters correctly.
520 $a Finally, the semi-mechanistic single-phase flow model was successfully extended to multiphase flow by using appropriate velocity and length scales. The particle transport model for multiphase flows developed resulting from this extension was compared to the experimental data obtained in the current study in both air-water and air-viscous liquid flows. It was shown that, in comparison to the available multiphase flow models in the literature, the new model improves particle transport in multiphase flow critical velocity predictions significantly.
