Numerical Study of Isothermal Gas-liquid Two-phase Bubbly Flow

More about the book

The book explores the application of computational fluid dynamics (CFD) in engineering, specifically focusing on gas-liquid two-phase flow. It emphasizes the two-fluid model, which distinguishes between the phases using separate transport equations for accuracy. Critical to this model are the closure terms that describe interfacial interactions, including turbulence modeling, driving forces, and interfacial area concentration. The research investigates the effectiveness of the two-fluid model and its closure terms in simulating both vertical and horizontal bubbly flow conditions.
