Multiphase Chapter 3: Volume-of-Fluid (VOF) Method
The Volume-of-Fluid (VOF) method is a cornerstone of free-surface modeling in CFD. It tracks the motion of interfaces between immiscible fluids—like air and water—by solving a single set of flow equations and evolving a scalar volume fraction that marks how much of each phase fills a cell. This approach enables realistic simulation of sloshing, filling, jet breakup, and dam-break flows without deforming the mesh. In ANSYS Fluent, VOF offers multiple schemes for time integration and interface reconstruction, balancing sharpness, stability, and computational cost
Multiphase Chapter 2: Mixture Model
The Mixture Model represents multiphase flow as a single continuous medium while preserving the essence of how its components drift, exchange, and transform within it. This chapter connects the mathematics of the model with its physical meaning — showing how mass, momentum, and energy transfer intertwine with interfacial phenomena, and how ANSYS Fluent applies these ideas in cavitation, wet steam, and condensation analyses.
