Velocity Correction Scheme for All Speed Flows
Abstract We present a velocity correction scheme that is suitable for the simulation of the broad range of Mach number flows. The scheme is based on the primitive variable no-iterative…
Periscope CFD simulations and comparison against experiments
Abstract Computational Fluid Dynamics (CFD) is a useful tool for predicting flow in cases where experimental measurements can be difficult or costly to conduct, such as measuring the wake from…
Improvements to numerical schemes in Caelus
Abstract The Caelus library is a general purpose numerical framework for the solution of the continuum mechanics problems. The framework is a derivative of the OpenFOAM® library with an emphasis…
Verification and Validation Caelus – Incompressible Solvers
Abstract Recent years have witnessed a significant proliferation of numerical libraries being used in computational continuum mechanics. While the appearance of open source codes in general, is a positive development,…
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.…
Scheme improvements in Caelus library
Abstract We present improvements to several core numerical scheme in the Caelus library that are a first step in improving robustness and accuracy for meshes with less than optimal quality.…
SLIM – Fast Transient Solver for Incompressible Turbulent Flows
Abstract This paper presents a fast transient solver suitable for the simulation of transient turbulent flows. The main characteristic of the solver is that it is based on the projection…
