CPerf
CPerf is an application for thermodynamic analysis and modelling of centrifugal compressors, gas turbines and turboexpanders. Features include:
  • Evaluates compressor and gas turbine performance using vendor performance maps.
  • Up to three compressor bodies (stages).
  • English or SI units.
  • Isentropic and Polytropic calculation options.
  • NIST REFPROP or Redlich-Kwong equations of state and transport properties.
  • Corrected speed and calculation option.
  • Efficiency and Work Factor versus Q / N plots.
  • Solve for compressor pressures and flows limited by driver power or speed.
    • ​User adjustable power, efficiency and speed deviations from vendor predictions.
    • User adjustable interstage pressure drops and side stream flows.
  • Gas turbine or electric motor drive (VFD or Vorecon) options.
  • Turboexpander gas composition, flow and power solvers.
  • Anti-Surge Valve flow evaluation.
  • Read data directly from the unit PLC by OPC or Logix built-in driver.
  • Import data from .csv or .log files.

​The CPerf evaluation license available for download below is fully featured except that the user is prevented from changing the compressor head/flow map and turbine performance model table. Please contact me if you are interested to obtain a full license for CPerf.

Site licenses of CPerf are available. We can work with your IT department to make CPerf available within your company's internal software distribution system.

CPerf Tutorials are available here.
