ANSYS BladeModeler 11.0 Technical Specifications

Initial Sizing Tools

Two new meanline design tools are now included with ANSYS BladeModeler software:

PCA Engineers Vista CCD for centrifugal compressors
- Given the compressor duty — mass flow, pressure ratio, etc. — and geometric constraints, the program will configure the compressor impeller geometry and provide essential non-dimensional performance parameters — specific speed, specific flow, etc.
- Blade geometry is output directly to BladeGen

PCA Engineers Vista CPD for centrifugal pumps and volutes
- Given the pump duty — flow rate, head, speed, etc. — and geometric constraints, the program will configure the pump impeller and volute geometry and provide essential non-dimensional performance parameters — specific speed, suction specific speed, head coefficient, etc.
- Blade geometry is output directly to BladeGen
