Ansys CFX Key Features

Streamlined workflows with integrated blade design to aid in the optimization of your design.

From template to mesh to a robust result, streamline your workflow with our blade design tools or software partner offerings. For the best product changes, our turbo workflows provide design tools and optimization methods.

Improve the safety of rotating components through accurate and high-fidelity aeromechanical simulations.

Performing aeromechanical simulations early in the product design and development process helps improve the safety and the durability of rotating components. Transient blade row (TBR) methods are used to reduce geometries from full-wheel to a simple single passage. Aeromechanical simulation problems can be solved through time marching or harmonic balancing.

There are several turbulence models to choose from, helping you to find the right one for your needs. Ansys CFX includes the industry leading Generalized k-ω (GEKO) model which is a ground-breaking concept that uses tunable coefficients that can be adjusted to different flow regimes.

Validated models for bubble formation, phase shift, drag and non-drag forces are used to accurately model wall boiling and measure the critical heat flux.

Get the most accurate results with real gas and fluids properties.

The advanced material simulation capabilities of CFX assist in producing the most reliable performance. To effectively address changes in material properties, adaptive methods can be used to construct real gas and fluid property tables from the REFPROP database (near critical point, for example). The built-in IAPWS database can be used to pick liquid water and steam properties.
