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.

The Fidelity Flow 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.

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.
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.
