Design Wizard Technology
COMPAL's unique Design Wizards lead the user step-by-step through the design, analysis, or data reduction process.
Modeling
COMPAL supports two-elements-in-series (TEIS) rotor diffusion modeling, two-zone loss modeling, disk friction, exit mixing, radial and axial stator diffusion/losses, volutes, inducer choke, stall, thrust, and other fundamental fluid dynamic aspects of compressor performance.
True-Scaled Meridional View of Stage
The compressor stage is shown in a true-scaled view.
Integrated Performance Map Plotting
Powerful and flexible plotting of performance maps allows quick review of performance and comparison of multiple designs or analyses versus test data. Maps are updated automatically with any geometry change.
Easy Editing
Parameter entry is accomplished by double-clicking on the appropriate component in the meridional picture.
Tabular View of Results
Results may be viewed in a flexible, spreadsheet-like tabular view. Tables are customizable through separate "filters." Users can create any number of filters, selecting what to display as well as customizing the labels.
Axial View with Velocity Triangles
Blade angles and velocity triangles may be viewed at both the impeller inlet and exit.
OLE Automation Support
Control of COMPAL can be accomplished from an external program through industry-standard Object Linking and Embedding (OLE) automation. Full control of data entry, program execution, and result retrieval is supported through OLE automation. External programs can be written in Visual Basic, C++, FORTRAN, or any other language which supports Microsoft's OLE standard.
Multistage Capability
Multistage analysis and data reduction are supported. A variety of multistage performance maps are available within COMPAL.
Preliminary Mechanical Analysis
COMPAL provides the user with an initial calculation of mechanical properties of the design. Stress, vibration, and fatigue limit estimates are rapidly provided and access a wide database of customizable material properties.
COMPAL is a Real Fluid Program
Real Fluid properties can be calculated in COMPAL using the optional DB Robinson Real Fluid property routines. Users can also incorporate their own proprietary fluid properties.
Direct Integration with AxCent®
The user can start AxCent automatically from within COMPAL, with 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.
