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.
DeepMind’s “Disproof” of Navier-Stokes: Euler Blow-Ups and Why It’s Overhyped
DeepMind and collaborators used physics-informed neural networks to uncover unstable singularities in idealized fluid equations (Euler)—the knife-edge cases where solutions blow up only under perfectly tuned conditions. I summarize what they actually did, what it means (and doesn’t) for the Navier–Stokes Millennium Problem, and why the media buzz may feel overhyped from an engineering/CFD point of view
Multiphase Chapter 1: Introduction to Multiphase Flow
Multiphase flows occur when gas, liquid, or solid phases coexist and interact through momentum, heat, and mass transfer. This chapter introduces the main regimes and explains how they are modeled in CFD using ANSYS Fluent. From simplified mixture models to detailed Eulerian formulations and interface-capturing VOF methods, the focus is on understanding the assumptions, strengths, and limitations of each approach. Practical guidelines for model selection and industrial examples help connect theory to real-world applications such as bubble columns, sprays, fluidized beds, and free-surface flows
Turbulence Chapter 5: Scale-Resolving Simulations (SRS)
This chapter covers Scale-Resolving Simulation (SRS) methods, which aim to resolve the large turbulent structures in a flow while modeling the smaller ones. The summary includes classical LES, wall-modeled and embedded LES, hybrid models like DES and SBES, and scale-adaptive approaches such as SAS. Application notes and model selection guidelines are also included.
