Weaving In and Out
Ansys CFX lets engineers investigate thermal properties of new and complex turbine blade geometries.
“Other codes that were tried in this application often did not converge at this node spacing [0.001mm]. The researchers validated the CFD results against a test problem consisting of a planar jet impinging on a flat plate and achieved very good correlation.”
New manufacturing methods have opened the door to more effective turbine cooling channel geometries. The new geometries will lead to better performance and efficiency but are more complex. To achieve highly accurate results, a team of Purdue engineers turned to Ansys CFX.
The engineers executed key computations with little turnaround time. With the extra time, they could perform more in-depth comparisons and run further simulations to fully optimize their product. Ansys CFX gave them the tools to land on a multi-mesh “weave” design. The new turbine design runs with much cooler blades and has been implemented at the Air Force Research Laboratory.

What's New
Automated Hybrid Meshing for Turbomachinery Blades
Ansys TurboGrid's automated hybrid meshing technology has been extended to support complex blade tips such as squeeler tips, end-wall contouring and large blade root blends.
Pre and Post-processing Performance Gains
Multithreading improves performance for pre and post processing for TurboGrid, CFX-Pre and CFD Post. Results show speed-ups of 4.5X for file reading and writing and 3X for turbomahinery report creation.
Streamlined Optimization Studies
Perform optimization studies using the CFX solver in Ansys optiSLang using the native CFX plugin (beta)
Ansys CFX CAPABILITIES
Ansys CFX is the industry leading CFD software for turbomachinery applications
Ansys CFX’s advanced physics modeling capabilities help engineers solve the most complex challenges in turbomachinery applications. This powerful software has been extensively validated and is renowned for its robustness and accuracy. Streamlined turbo setups and blade design tool integration ensures that you have more time to spend optimizing your design. Whether it’s used for blade design optimization or advanced material modeling, CFX is the reliable tool you can use to save both time and money.
Key Features
Solve a variety of fluids-related problems with high levels of accuracy and unmatched speed
- Blade design and optimization
- Aeromechanics
- Industry leading turbulence modeling
- Nuclear Wall boiling
- Advanced material modeling
Streamlined workflows with blade design integration to help optimize your design.
Streamline your workflow starting from our blade design tools or software partner offerings, from design to mesh to a robust result. Design tools and optimization methods are integrated into our turbo workflows for the best design improvements.
Improve safety of rotating components with accurate aeromechanical simulations.
Early aeromechanical simulations help improve safety and durability of rotating components. Transient blade row (TBR) methods are used to reduce geometry from a full-wheel to a single passage. Problems are solved with time marching or harmonic balance.
A wide range of turbulence models are available, allowing you to choose the best model for your application. CFX also includes the industry leading Generalized k-ω (GEKO) model. GEKO is a revolutionary concept with tunable coefficients that can be adjusted to different flow regimes.
Accurately model wall boiling and calculate the critical heat flux using validated models for bubble growth, phase change, drag and non-drag forces.
Get the most accurate results with real gas and fluids properties
CFX’s advanced material modeling help generate the most accurate results. Real gas and fluid property tables can be created from the REFPROP database using adaptive methods to efficiently resolve changes in material properties (near critical point, for example). Liquid water and steam properties are selectable from the built-in IAPWS database.
