FLOW REGIME

Multiphase flow is defined as the simultaneous flow of two or more phases (e.g., gas, oil, water, or solid). When operating petroleum production facilities such as pipelines, this is a normal flow. As a result of complexity, the physical phenomenon governing them than that of single-phase flow, a production engineer's ability to effectively conduct a research on this system would necessitate a thorough understanding of the system to aid in its optimal operation. The study's objective is to create a CFD model using the ANSYS version 19.1 platform, validate the model with experimental data, and review studies and the employed model to estimate the critical velocity of a sand particle in a slurry flow and the particle's erosional effect for a pipe of a particular diameter (0.07m) Based on literature reviews and comparative studies, the Eulerian model with Reynold Stress Model (RSM) turbulence closure was chosen as the best model to analyze multiphase fluid flow. The research combines validation work in all feasible scenarios to evaluate the creation of the CFD model with a parametric analysis to look at the effects of various factors on particle deposition. Pipe diameters of 0.02 – 0.07m, continuous phase flow rates of 0.1-1 m/s, and other parameters were investigated. In conclusion, ANSYS version 19.1 platform is a valid way of analyzing multiphase flow in pipelines, proven using historical experimental data. Laminal flow is suitable for suitable fine particle and yields minimal erosion when its velocity is above the particle critical velocity. While coarse particles are transmitted by turbulence flow, with reducing erosion as the velocity increases above the critical velocity
