Detailed Pumps and Compressors

Modeling and Simulation of Pumps and Compressors

GT-SUITE is the ideal tool to model pumps and compressors for all important design considerations including the study of detailed flow and thermodynamic behavior, as well as the analysis of machine response in a larger system. GT-SUITE models are used across a wide range of applications including hydraulics, fuel, lubrication, cooling, transmission, HVAC, gas processing, and aftertreatment systems.

This machinery is studied in detail to predict performance, flow and pressure pulsations, NVH issues, friction, and support bearing performance. Many types of pumps and compressors can be modeled including positive and variable displacement, including:

  • Gerotor
  • Vane
  • External Gear
  • Reciprocating
  • Swashplate
  • Scroll
  • Screw
  • Roots Blower
  • Crescent
  • Claw
  • And more!

Product Highlights

  • Detailed flow pulsations predicted from geometry
  • Automated model building from CAD for vane, gerotor, scroll, and external gear machines
  • Positive and variable displacement
  • Simple pumps with map or displacement input options

Key Predictions

  • Performance vs. speed, pressure rise and temperature
  • Flow and pressure pulsations
  • NVH issues, resonance, fluid borne noise
  • Dedicated friction model for vane and gerotor style machines
  • Interaction with relief valve dynamics
  • Bearing loading due to internal pressurization

Advanced Features and Applications

  • Any fluid can be used: gas, liquid, refrigerant, two-phase with injection
  • Species transport
  • Cavitation and free/dissolved gas
  • Detailed pumps and compressors can be run standalone or integrated into system model
