Turbulence models

Churn turbulent flow

Churn turbulent flow is a two-phase gas/liquid flow regime characterized by a highly-agitated flow where gas bubbles are sufficient in numbers to both interact with each other and, while interacting, coalesce to form larger distorted bubbles with unique shapes and behaviors in the system. This flow regime is created when there is a large gas fraction in a system with a high gas and low liquid velocity. It is an important flow regime to understand and model because of its predictive value in nuclear reactor vessel boiling flow. (Wikipedia).

What Is Turbulence? Turbulent Fluid Dynamics are Everywhere

Turbulent fluid dynamics are literally all around us. This video describes the fundamental characteristics of turbulence with several examples from nature and from engineering. We discuss how turbulent fluids are unsteady, three-dimensional, mixing, and multiscale. We also describe how

What Is Turbulence?

Physicists use the Navier-Stokes equations to describe fluid flows, taking into account viscosity, velocity, pressure and density. But because of turbulence in fluids, proving that the equations always make sense is one of the hardest problems in physics and mathematics. Read about the epi
