Screw Machine Modeling and Simulation

GT-SUITE is the ideal tool to model screw machine thermodynamics, flow pulsations, friction, and integration with other systems. 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. Thermodynamic chamber models are then run in GT-SUITE or SCORG and can be further utilized to analyze flow pulsations and prop muffler design to attenuate undesired NVH noise. Other important factors are also analyzed such as the optimization of tribological bearing performance with a fast running or high-fidelity thin EHD bearing model.
