Pigging Oil Flow in a Pipeline CFD Simulation

Explore the fundamentals of pipeline pigging operations through our ANSYS Fluent simulation module. This training focuses on the multiphase flow dynamics in a pipeline during a static pigging scenario, providing essential insights into oil and gas engineering applications.

Key focus areas include:

Multiphase flow modeling: Analyze the interaction between oil, gas, and potential debris within the pipeline in the presence of a stationary pig.

Phase distribution: Examine how the presence of a pig affects the distribution of different phases in the pipeline.

Pressure drop analysis: Investigate the impact of the pig on pressure gradients along the pipeline.

Flow pattern visualization: Study the flow patterns around the pig and how they differ from normal pipeline flow.

Fluid property effects: Understand how varying fluid properties influence the multiphase flow behavior around the pig.

This case study offers hands-on experience in simulating basic pipeline pigging scenarios using ANSYS Fluent. You’ll develop skills in setting up multiphase models, defining appropriate boundary conditions, and interpreting results that connect theoretical fluid dynamics concepts with practical mechanical engineering applications.

The simulation provides insights into:
