Turbulence is a complex phenomenon that occurs in most engineering applications involving fluid dynamics. It is characterized by the irregular and chaotic motion of fluid particles, which can cause significant fluctuations in velocity and pressure. Until now, there has not been a single and practical turbulence model that can reliably predict all turbulent flows with sufficient accuracy. whereas many turbulence models have been developed from the perspective of finding different compromises between...

SAS cutting on your computational budget in an unsteady*manner

Posted May 18, 2017 at 16:47 by Avr.Tomer

The following is taken from*CFD ISRAEL*blog (thoughts of a CFD blogger), addressing a branch of Scale Resolving Simulation known as 2nd generation URANS.
The specific SAS model is a*2-equation*unsteady RANS model, able to get very good quantitative results for many unsteady flows even on a relatively coarse mesh.
