Flow Simulation Study For Rotating Cage Equipment

Corrosion is an unavoidable event that occur specifically in pipelines. There are multi-faceted factors contributing to corrosion in pipelines. Several techniques can be used to simulate the pipeline flow. One of the methods is Rotating Cage (RC), which can be used to simulate pipeline flow by rotat...
