The severity of erosion resulting from the presence of solid particles in a carrier fluid depends on a multitude of factors. Fluid properties and rates, particle properties and rates as well as geometry type, size, and material all affect the amount of erosion. For a multiphase carrier fluid, additional parameters such as the flow regime also impact the amount of erosion. Additionally, experiments have shown that pipe orientation can also impact the severity of erosion in multiphase flow. The differences result from changes in flow characteristics such as distribution of film thickness around the pipe for annular flow. Changes in the flow characteristics can also affect the distribution of the solid particles. The current work provides experimental data demonstrating the effect of orientation on erosion and proposes an extension to an existing erosion prediction model to predict erosion in elbows for annular flow that accounts for upstream pipe orientation, vertical or horizontal. The severity of erosion is an indicator of the potential severity of erosion/corrosion damage.
