Multi-Fluid Modeling
Model gas, liquid, refrigerant, and two-phase flows with injection, all within the same framework
Solutions
Pumps and Compressors
Simulate pumps and compressors in GT-SUITE — model detailed flow, cavitation, and thermodynamic behavior across hydraulic, fuel, lubrication, and refrigerant systems.
Wide Range of Applications
GT-SUITE delivers detailed simulation capabilities for pumps and compressors across a broad range of industries and system types. Models are applied to hydraulic systems, fuel delivery, lubrication circuits, cooling systems, transmission systems, HVAC, gas processing, and aftertreatment systems — enabling engineers to analyze both individual components and fully integrated system behavior within a single simulation environment.
GT-SUITE is the ideal tool to study detailed flow and thermodynamic behavior for any pump or compressor application. Each machine type is analyzed in depth to predict performance characteristics, flow and pressure pulsations, noise, vibration, and harshness (NVH) issues, friction losses, and bearing performance resulting from internal pressurization.
Pump and Compressor Simulation Capabilities
- Detailed flow and pressure pulsations predicted directly from machine geometry, enabling accurate NVH analysis and fluid-borne noise assessment without reliance on experimental pulsation data
- Automated model construction from CAD geometry for vane, gerotor, scroll, and external gear machines, significantly reducing setup time and minimizing manual input errors
- Full support for positive and variable displacement machines within a unified modeling framework, covering a wide range of pump and compressor types including reciprocating, swashplate, screw, roots blower, and scroll machines

Pump & Compressor Modeling FAQ
Answers to the most common technical questions from engineers evaluating GT-SUITE for pump and compressor applications
-
What types of pumps and compressors can GT-SUITE simulate?
GT-SUITE models a comprehensive range of positive and variable displacement pump and compressor technologies, including scroll, screw, reciprocating, vane, gerotor, swashplate, external gear, crescent, roots blower, rotary, and claw machines, with support for both simple performance-based and detailed chamber models across automotive, hydraulics, lubrication, fuel, cooling, and HVACR applications.
-
How does GT-SUITE handle the complex physics involved in pump and compressor modeling?
GT-SUITE’s Navier-Stokes flow solver simultaneously resolves conservation of mass, momentum, energy, and species with exceptional numerical stability , capturing pressure pulsations, cavitation, transient aeration, and species transport across hydraulic, lubrication, fuel, and HVACR applications .
-
Can GT-SUITE integrate pump and compressor models with other vehicle or system components?
Yes — models can be seamlessly coupled with engines, HVAC systems, hydraulic circuits, electrical systems, and mechanical components like shafts and bearings. This makes it possible to study complete system behavior, optimize component interactions, and predict auxiliary losses when pumps are crankshaft-driven.
-
What level of modeling detail and automation does GT-SUITE provide?
Modeling flexibility spans simple performance maps to highly detailed geometric models. Automated model building through GEM3D extracts geometry directly from CAD for scroll machines, twin screw compressors, and other complex geometries, while pre-built libraries and discretization tools cut setup time without sacrificing accuracy.
