Verification and Validation of Caelus – Incompressible Turbulence Models
Abstract Incompressible turbulence models have been implemented in Caelus, a general purpose numerical framework, to enable computations of turbulent incompressible flows. While other open source libraries and CFD solvers implement…
Cyclone simulation and validation using Caelus
Abstract Cyclone separators play a dominant role in the industrial separation of dilute particles from an incoming gas flow. The incoming flow enters tangentially and accelerates on its way down…
A two equation VLES turbulence model with near-wall delayed behaviour
Abstract Turbulence is a phenomenon that occurs frequently in nature and is present in almost all industrial applications. Despite significant increase in computational power in modern processors, Reynolds averaged Navier-Stokes…
Bubble Column – Euler-Lagrange Large Eddy Simulations
Abstract Bubble column reactors are widely used in the chemical and biochemical process industries, but numerous examples can be found in petroleum, pharmaceutical, agricultural, biochemical, food, electronic, and power-generation industries…
