AxSTREAM for Axial and Mixed Flow Compressor and Fan Design

Key Features and Benefits

• The scope of axial compressor design and analysis: flow path with normal (rotor-stator) and single row stages, mixed flow (axial/radial) flow path, multi-section flow path, flow path with counter-rotating rotors.
• Axial compressor flow path preliminary design/sizing/optimization, choosing the optimal number of compressor stages and cascade angles.
• Multistage flow path meanline analysis and optimization with support of “as-designed” and “off-design” operational conditions.
• Meanline analysis of combined axial-radial compressor flow path.
• Turbomachinery flow path throughflow analysis and stage throughflow analysis with search for optimal blade twist using the optimization methods through design cycle in the interactive mode.
• Axial compressor analysis and optimization in the “off-designed” mode using the integrated optimizer based on the design-of-experiment (DoE) methodology.
• Performance map generation including flow path of variable geometry: vanes/blades rotation schedules.
• Generation, interactive editing, and optimization of the cascades. Flow and boundary layer calculation.
• 3D airfoil design in the automatic and interactive modes with geometric and strength criteria monitoring; 3D fan and compressor blade design with custom lean and sweep.
• Custom profiles database.
• Reusable axial compressor stages libraries.
• Experimentally confirmed empiric and custom loss models.
• Embedded fluids library with custom extension option.
• Embedded material library with custom extension option.
• Export of 3D blade geometry for detailed CFD analysis to NUMECA, CFX, and Fluent solvers; export of properties of fluids in a table for CFD analysis to CFX™.
• Export of 3D blade geometry to CAD in IGES formats.
• Express 3D structural and modal analysis (including Campbell diagram) of axial compressor blade via embedded FEA module with automatic mesh generation – AxSTRESS.
• 3D CFD flow analysis via embedded CFD calculation solver AxCFD with automatic mesh generation and post-processing of obtained results.
• Flow charts and charts for blade loading on Profiling module.
• Detailed Mollier diagram.
• 1D/2D Streamline solver allows finding compressor surge, stall and choke. It is capable to calculate transonic and subsonic stages of compressor
• AxMAP helps develop compressor map and can show dependence of pressure ratio of mass flow and rotation speed.
