CFD-15. Scale-Adaptive Simulation Model
With this entry on Computational Fluid Dynamics (CFD) we finish the series of cases related to turbulence modelling. In this example we will deal with the SAS (Scale-Adaptive Simulation) method that solves turbulent structures by adapting the resolution scale to the mesh size and time step used. In this way, a solution similar to that […]
CFD-14. Flow transition with hybrid turbulence models.
In this new entry on Computational Fluid Dynamics (CFD) we will study an advanced turbulence model that combines the ideas of the hybrid LES-RANS model with the ability to represent laminar-turbulent transition effects. We will perform a study with an unsteady transition flow around a cylinder. The steps to follow can be found in the […]
CFD-09. Curved channel flow. SST turbulence model.
In this post on Computational Fluid Dynamics (CFD) we begin a series of posts dedicated to studies where flow turbulence plays a fundamental role. In this first example we study the flow through a curved channel, where the SST (Shear Stress Transport) turbulence model may be applied. As shown in the picture, we will use […]
CFD-06. Inverted flow. Turbulence model.
In this post on Computational Fluid Dynamics (CFD) we are going to perform a common benchmark of CFD analysis, the study of inverted flow after a step. It reflects the importance of choosing the right turbulence model in CFD simulations. We will use the Acusolve software with the Hyperworks CFD pre-processor. This study also has […]
