Stratified gas-liquid-solid flow modeling - application to hydrate slurry flow

摘要

In this paper, a 4-layer mechanistic model for solid-liquid-gas flow under stratified conditions is presented. In the model, each phase is treated separately and continuity and momentum equations for each phase/layer are solved. Three possible flow patterns for the solids distribution in the liquid phase are considered: heterogeneous flow, flow with moving bed and flow with stationary bed. Preliminary model validation with data gathered in the University of Tulsa flow assurance loop is presented. The model could also be applied to other disciplines, such as cuttings transport, sand control and solids separation.
