Best-in-class turbomachinery design tools

Engineers looking to combine speed and accuracy for their virtual turbomachinery designs trust Cadence for their toughest challenges.

We have designed a unique toolset that encompasses a complete end-to-end solution: 1D to 3D, Meshing, CFD and Optimization, all in one single environment. Thanks to more than 75 years of expertise in rotating machinery, the environment displays an unsurpassed ease-of-use and accuracy.

Configurations range from multi-stage axial to radial to mixed-flow configurations (compressors, turbines, pumps, fans, propellers or contra-rotating propellers).

The Omnis™/Turbo & Agile solution includes access to the trusted FINE™/Turbo and FINE™/Agile tools.

Preliminary and detailed design

Extend the power of the Turbo CFD software with integrated preliminary and detailed design tools of the Agile package, thanks to our parnership with Concepts NREC.

Concepts NREC’s Computer-Aided Engineering (CAE) modules each have a unique Design Wizard that leads the user through all the necessary steps for design, analysis, and data reduction.

The meanline design can then easily be sent to AxCent® for detailed 3D design.

Structured & Unstructured seamlessly combined

The structured Turbo solver for rotating parts Omnis™/Turbo with Omnis™/AutoGrid structured meshes, offers unsurpassed speed and accuracy.

Combined with the unstructured Omnis™/Open-DBS solver, with Omnis™/Hexpress meshes, for peripherals such as volutes, inlets, etc.. the complete application is solved using the most optimal approach for each part.

Components range from multi-stage axial to radial to mixed-flow configurations: compressors, turbines, pumps, fans, propellers, contra-rotating propellers…

Non-Linear Harmonic method

KJ66 static pressure

Gaining 3 orders of magnitude in solving speed for unsteady simulation.

With the Non-Linear Harmonic method, users can solve transient behavior 100 times faster, capturing clocking, blade row interactions, tonal noise, inlet distortion etc…

This unique technique computes the unsteady flow field by means of the Fourier decomposition of the periodic fluctuations, based on a pre-selected number of harmonics, typically associated with the blade passing frequencies and their multiples.

Users choose the frequencies and as many rotor-stator interactions as needed for their analysis.

Turnaround time 20x faster than any other solution on the market

The Omnis/Turbo CFD solution is optimized by scaling linearly on thousands of CPU cores, as well as on GPU (the latter provides a 2,4 times speed-up vs CPU).

Combined with our patented CPUBooster™ technology, a unique convergence acceleration technique, computation time is reduced even further, by a factor 3-5.

This package renders the solution up to 20 times faster than any other solution on the market.

Simplifying complex physics

Cavitation inception: Left, no local refinement – Right, dynamic mesh adaptation

Solutions for some of the more challenging topics that CFD engineers still face today, such as:

• Conjugate Heat Transfer (CHT)

• Combustion (premixed and non-premixed)

• Cavitation

• and many more…

Full-engine 3D CFD simulation

With the purpose to meet the future requirements of aircraft engines in terms of low emissions, high reliability and efficiency, a novel highly efficient fully-coupled RANS-based approach has been developed, enabling the simulation of a full aero-engine within a single code.

One of the advantages of a fully coupled approach over a component-by-component approach, is that the boundary conditions at the interfaces do not need to be guessed.

Computation of a full engine using Omnis™/Open-DBS’s NLH and combustion models

A Smart Interface methodology ensures a direct coupling between the different engine components, compressor- combustor-turbine, and allows the CFD models to vary between each component within the same CFD code.

For the simulation of the combustion process, the Flamelet Generated Manifold (FGM) method is applied. While the approach is superior to classical tabulated chemistry approaches and reliably captures finite-rate effects, it is also computationally inexpensive.

The Nonlinear Harmonic method is used to model the unsteady interaction between the blade rows as well as the influence of the non-homogeneities at the combustor outlet on the downstream turbine blade rows. This method is 2 to 3 orders of magnitude faster than a classical URANS simulation.

Fluid-Structure Interaction

Set-up and start complete FSI simulations using only one software. FSI-OOFELIE couples the Finite Element solver Oofelie of Open Engineering with Cadence’s fast and accurate parallel flow solver Omnis™/Open-DBS with OpenLabs™ into one single environment.

The direct coupling within one single environment, allows for great gains in set-up time and reliability.

Aero-Vibro-Acoustics analysis

FINE™/Acoustics is a complete simulation suite for the analysis of a broad range of industrial applications involving Acoustics, Vibro-Acoustics and Aero-Acoustics.

Simultaneous tonal noise source and propagation analysis with the Non-Linear Harmonic method (NLH).

Broadband flow-noise source reconstruction based on steady RANS. Noise propagation with Boudnary Element Method (BEM) and Finite Element Method (FEM).

Optimization and Uncertainty Quantification

Automatic pump optimization with a limited number of design iterations

Maximizing performance and minimizing performance variability

The optimization framework FINE™/Design3D provides access to the Minamo optimization engine, boasting a number of cutting edge features in terms of Design of Experiments (DoE), model reduction, optimization algorithms and post processing.

Take into account uncertainties and quantify the influence of variability on the simulation prediction to ensure your optimization is in real life conditions.
