COMPAL ®

Meanline design optimization for centrifugal and mixed-ow compressors

COMPAL allows you to perform meanline anal-

ysis for centrifugal or mixed flow compressors.

In COMPAL you can design the stage, analyze

the performance, and reduce laboratory datain order to refine your input parameters.

You have a maximum degree of flexibility in

modeling the performance of your machine,

according to a variety of different, but quali-

fied, performance modeling approaches.

COMPAL allows you to easily migrate your

compressor design into the AxCent™ appli-

cation for further blade design and fluid

dynamic analysis.

COMPAL supports

• Radial or axial inlet guide vanes• Open or closed impellers

• 2D or 3D impellers

• Front and rear seals (multiple)

• Diffusers (up to 20)

• Exit elements

• Various leakage paths

• Multistage compressors

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-Element-in-Series

(TEIS) rotor diffusion modeling, two-zone loss

modeling, single-zone rotor loss modeling,

disk friction, exit mixing, radial and axial

stator diffusion/losses, volutes, inducer choke,

stall, thrust, and other fundamental uid

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 exible plotting of performance

maps allows quick review of performance

and comparison of multiple designs or analy-ses versus test data. Maps are updated auto-

matically 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 exible,

spreadsheet-like tabular view. Tables arecustomizable through separate “lters.” Users

can create any number of lters, selecting what

to display as well as customizing the labels.

Axial View with Velocity TrianglesBlade 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 indus-

try-standard Object Linking and Embedding

(OLE) automation. Full control of data entry,

program execution, and result retrieval is sup-

ported through OLE automation. External pro-

grams can be written in Visual Basic, C++,

FORTRAN, or any other language which sup-

ports Microsoft’s OLE standard.

Multistage Capability

Multistage analysis and data reduction are

supported. A variety of multistage perfor-

mance maps are available within COMPAL.

Preliminary Mechanical Analysis

COMPAL provides the user with an initial calcu-

lation of mechanical properties of the design.

Stress, vibration, and fatigue limit estimatesare rapidly provided and access a wide data-

base 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 incor-

porate their own proprietary uid properties.

Direct Integration with AxCent

The user can start AxCent automatically from

within COMPAL, with initial geometry trans-

ferred 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.
