Screw Machines
GT-SUITE models screw machine thermodynamics, flow pulsations, friction, and system integration, giving engineers the accuracy needed to design better compressors, pumps, and expanders.
MULTI-PURPOSE MODELING
These screw machines are modeled as a compressor, pump, or expander and consider pure gas, liquids, two-phase mixtures, and two-phase refrigerants. Models are used across a wide range of applications including hydraulics, fuel, lubrication, cooling, transmission, HVAC, gas processing, and aftertreatment systems.
In order to build accurate chamber thermodynamic models, information about the screw machine volume geometry, inlet and outlet porting, and clearance gaps must be known. This information can be calculated from CAD, inhouse tools, or other 3rd party tools such as SCORG, an industry leading screw machine modeling software.
GT-SUITE now fully integrates with SCORG, a unique software for the design and analysis of positive displacement screw compressors, pumps and motors. With this integration, inputs calculated from screw geometries in SCORG are automatically populated in the GT-SUITE interface.
