Mixed Flow Regime Modeling in Ansys Fluent | Ansys Webinar

In the oil and gas sector, CFD modeling of mixed flow regimes and regime transitions in gas–liquid systems and gas–liquid flows often involves transient patterns, such as slug flow, annular flow, etc. These conditions often occur when more than one flow topology —droplet, bubbly or separated flows — exist. Such mixed flow regimes are more pronounced when the flow path involves bends, junctions and inclines. These flows can often involve regime transitions as well. The ability to predict mixed flows reliably is crucial for flow assurance and nuclear safety.

In this webinar, we discuss the recent advances in mixed flow regime modeling in Ansys Fluent, namely AIAD and GenTOP models. We discuss the background and applications of these models, then show examples of each.
