AxCent® is used for detailed 3D geometric design and for rapid flow analysis of multistaged axial and radial turbomachinery through streamline curvature. AxCent employs powerful features for axial, mixed-flow, and radial geometries that can be combined to design almost any turbomachinery.
AxCent easily handles the most complex blade geometry. A partial list of blade design features include:
Other design features include:
Recent 3D features include:
AxCent includes several options for real-time interactive flow analysis:
Design before editing
Design after editing
And a number of CFD-based solvers:
Four-stage axial compressor case study showing results from both Throughflow and Blade-to-Blade solvers:
Throughflow ran in under 25 seconds - best for axial machines
Blade-to-Blade ran in approximately one minute. It works on either axial or radial machines and runs fastest on radial machines.
AxCent works through direct links with all Concepts NREC meanline programs including:
AxCent can be started from any Concepts NREC meanline program (once the geometry has been set up), and can link the AxCent geometry back to the meanline design to rerun the analysis and regenerate the performance maps. Additionally, using TurboOPT II, the AxCent geometry can be linked to an internal optimizer or to a third-party optimizer such as modeFRONTIER, Isight™, VisualDOC, and IOSO.
AxCent is fully integrated with Concepts NREC FEA stress analysis programs, Pushbutton FEA™. FEA stress, thermal and modal analysis can be conducted directly through the AxCent interface.
AxCent is also compatible with many commercial and open source software packages. Some examples include:
AxCent easily handles the most complex blade geometry. A partial list of blade design features include:
Blade stacking of 2D cross sections
Blade restaggering around an arbitrary axis
Bowed blading defined by hub-to-shroud bow profiles
Bowed or sculpted element with arbitrary number of mid-span sections
Variable tip clearance on either end of the blade
Flow cuts and radial trims
Swept leading/trailing edges
Multiple, offset, and independent splitter blades
Irregular blade/splitter configurations for noise reduction
Other design features include:
Parameterized volute geometry generation
Split duct geometry
Fillets with constant or variable radius and aspect ratio
Recent 3D features include:
Cutaway view allows real-time cross sections to be viewed as the design is edited
3D overlays permit viewing of current, real-time changes on a transparent overlay
AxCent includes several options for real-time interactive flow analysis:
Inviscid streamline curvature solvers, including Concepts NREC's Multi-Stream Tube Solver (MST), are recognized in the industry as the best for centrifugal pumps and compressors
MST puts the power of real-time analysis in your hands. It enables you to immediately visualize the consequences of design changes on velocity, temperature, and pressure. You can look at multiple iterations in seconds, rather than the hours necessary to export each design to CAD for CFD analysis.
Using MST, you can significantly reduce the overall design cycle time by providing an optimized iteration for validation, rather then the more traditional iterative process that requires a lot more back and forth.

AxCent is also compatible with many commercial and open source software packages. Some examples include:
FLUENT® - Direct export of geometry or CFD grids through native FLUENT format files
OpenFOAM® - Export of grid files and importation of output files through OpenFOAM formats
CAD Systems Export of IGES and STEP formats for seamless integration with virtually any CAD package
Isight - Link to Isight optimization via XML format or directly through Concepts NREC’s TurboOPT IIoptimization software
Import-export formats with Python scripting, XML format options, various other file output for seamless export to Concepts NREC CAM programs (the MAX-PAC suite)

We were working well with the OEM but even with our combined efforts, we were struggling to get a critical compressor to pass performance on their test stand. Although I'd never directly done business with Concepts NREC I was familiar with them and their capability so I chose to contact them when I came to the realization that we needed some objective insight. Concepts NREC fielded my cold call and immediately engaged their expertise in a complex problem that was also challenged by schedule constraints. They provided increased understanding of an already complex CFD which resulted in increased confidence that the proposed solution would succeed on the next test stand attempt (which it did!). We are pleased to have had the help of Concepts NREC and now have a well-performing compressor in our process.”
