CAE Radial Compressors
COMPAL® Preliminary design
A meanline approach is used to rapidly design and analyze radial and mixed-flow compressors for single or for multiple stages. COMPAL is used to design the compressor stage, analyze performance, refine parameters with data reduction, and model the machine according to a number of performance models. COMPAL's unique Design Wizard leads the user through all the necessary steps for design, analysis, and data reduction. The meanline compressor design can easily be sent to the AxCent® program for further blade design and fluid dynamic analysis.

Modeling
COMPAL supports two-elements-in-series (TEIS) rotor diffusion modeling through a two-zone loss modeling approach, disk friction, exit mixing, radial and axial stator diffusion/losses, volutes, inducer choke, stall, thrust, and other fundamental fluid dynamic aspects of compressor performance. Many alternative models are also available.
Integrated performance map plotting
Review design performance, analysis, and test data with flexibly plotted performance maps, updated automatically with each geometric change.
Easy editing
View the compressor stage in an active, true-scale meridional view. Edit the parameters by double clicking on the component in the meridional view. Also, edit parameters using a single text input/output file, a feature especially useful for optimization.
Tabular view of results
View the results in a flexible, spreadsheet-like table, customizable through separate filters. Create any number of filters, select what to display, and customize the labels as well.
Axial view with velocity triangles
View blades and velocity triangles at the impeller inlet and exit in a window view. View inlet velocity triangles for the hub, tip, or RMS radius, and exit velocity triangles for the primary and secondary zones, and mixed-out state.
OLE automation support
Control COMPAL from an external program through industry-standard Object Linking and Embedding (OLE) automation. OLE automation supports full control of data entry, program execution, and result retrieval. External programs can be written in Visual Basic, C++, FORTRAN, or any other language that supports the Microsoft® OLE standard.
Multistage capability
COMPAL supports multistage analysis and data reduction, and provides a variety of multistage performance maps.
A Real Fluid program
COMPAL calculates Real Fluid properties using optional DB Robinson Real Fluid Properties, NIST, or ASME Steam routines. Users can also incorporate their own proprietary fluid properties.
Direct integration with AxCent®
AxCent can start automatically from within COMPAL, with the initial geometry transferred automatically to AxCent. Changes in AxCent that affect the meanline analysis will cause the meanline analysis to be rerun and all performance maps to be regenerated.
