Best Practice Guidelines for the Generalized k-omega (GEKO) Two-Equation Turbulence Model in ANSYS CFD

Take control of turbulence in your simulations with the GEKO (generalized k-omega) two-equation turbulence model in ANSYS Fluent. GEKO provides users with the flexibility to tailor turbulence models to their applications using several free and tunable parameters. These can be adjusted over a wide range to match the simulation to specific physical effects, while preserving the underlying calibration. This technical paper provides a detailed description of GEKO and includes best practices for use and optimization.

GEKO – A New Paradigm in Turbulence Modeling

Since no single turbulence model is suitable for all flow applications, users must choose from a finite set of fixed models, hoping one fits their simulation. This white paper introduces GEKO (generalized k-ω), a revolutionary concept in turbulence modeling that gives you the flexibility to tailor turbulence models to your applications. Developed by turbulence expert Dr. Florian Mentor, GEKO provides several free, tunable parameters, which can be adjusted over a wide range to match the simulation to specific physical effects, while maintaining the underlying calibration for flat plates and mixing layers.

Nouvelle méthodologie de maillage dans ANSYS Fluent

Le maillage représente une étape cruciale dans la réalisation d’un calcul CFD. Pour les géométries complexes, le recours à un outil intégrant des algorithmes de maillage avancés peut s’avérer indispensable. ANSYS Fluent Meshing, le mailleur intégré d'ANSYS Fluent, est alors l’outil préférentiel.

Nombre de récents développements ont permis d’améliorer l’ergonomie de l’outil mais pour la première fois l'outil intègre des « Templates » simplifiant à l’extrême la méthodologie de maillage et offrant la possibilité à chaque utilisateur, indépendamment de sa maîtrise de l’outil, de bénéficier de la puissance de maillage d'ANSYS Fluent.

Durant ce webinar, nous verrons comment réaliser simplement le maillage de géométries complexes en utilisant les récents développement d'ANSYS Fluent Meshing.

ANSYS + volabo GmbH - Case Study

Read this case study to learn how VOLABO used multiphysics simulation software obtained through the ANSYS Startup Program to develop the first 48 V high power traction drive, which is 25 percent more efficient than conventional electrical drives and does not need rare earth magnets for production. What makes the ISCAD drive unique is the virtual gearbox that enables the motor to continuously adapt to the load profile and thus make better use of the battery capacity.

Cray and ANSYS Give Aircraft Takeoffs a Big Lift

Cray and ANSYS tackled the high-lift simulation challenge, working together on two high-lift prediction test cases developed by the AIAA CFD High Lift Prediction Workshop (HiLiftPW). The computational results — made possible by Cray XC supercomputing power and obtained with ANSYS Fluent — showed excellent performance: a 189-million-cell simulation completed in under two hours.
