The Three Elements of the EASy! for Compressors Design Suite
COMPAL®/PREDIG™
Design, Analysis, and Test Data Reduction for Compressors
COMPAL/PREDIG allows the engineer to perform meanline analysis for centrifugal or mixed flow compressors. In COMPAL/PREDIG, engineers can design the stage, analyze the performance, and reduce laboratory data in order to refine input parameters. Engineers have a maximum degree of flexibility in modeling the performance of machines, according to a variety of different, but qualified, performance modeling approaches.
COMPAL/PREDIG allows the easy migration of a compressor design into the CCAD/COMIG application for further blade design and fluid dynamic analysis.
CCAD®/COMIG®
Detailed Design of Blading and Flow Path for Incompressible
Flow
CCAD/COMIG, the second step of the compressor design process, automatically provides very good initial blade shapes that achieve the component performance predicted in COMPAL/PREDIG. The designer can either accept or improve upon this initial design. CCAD/COMIG uses an iterative approach to design and analyze the compressor geometries. Its fluid analysis combines specified losses with a quasi-3D inviscid flow analysis for fast results. CCAD/COMIG is completely integrated, importing COMPAL/PREDIG data and interfacing with mechanical analysis and CAD/CAM software, to produce better detailed designs in less time and at a lower cost.
Pushbutton CFD®
3D Viscous Analysis of Incompressible Flow
Pushbutton CFD is CFD for compressor design with a major difference. It is built right into CCAD and, with fully automatic preprocessing, CFD runs can literally be setup with one keystroke. Pushbutton CFD is designed to support rapid design iterations, with examples of three-dimensional viscous flow solutions taking less than 5 minutes on a modern PC. It relates geometric details of a design to fluid flow characteristics and component performance. Pushbutton CFD provides true tip-clearance representation. It can converge to user-specified flow rates or back pressure. Pushbutton CFD is the key to predictable compressor performance; allowing the performance of all designs to be optimized; avoiding problem designs; and troubleshooting existing hardware.
