SCORG v2024 alert: New Release and Webinar!

PDM Analysis Ltd is pleased to announce the new release and webinars for the latest version of its software, SCORG v2024. 


SCORG is an industry leading software for the design and analysis of screw compressors, expanders, pumps and motors. It offers unique capability to evaluate the performance and operation of positive displacement machines by use of Computational Fluid Dynamics and Thermodynamic Multi Chamber Model. It also allows you to produce a full 3D design of screw machines. SCORG will minimise efforts and maximise efficiency of the design process by enabling geometry analysis, preliminary thermodynamic evaluation, grid generation and design of positive displacement rotary machines.


This release is a significant step into design exploration. New features have been introduced to model Vacuum pumps with Quimby rotor profile as well as the 3D CAD design of screw compressor elements.

The major new features in SCORG v2024 are as follows:


  • Modelling of vacuum pumps with Quimby profile
    • Profile generation of Quimby profile traditionally used in vacuum pumps. It is now possible to generate Quimby rotor profile that suit the specific requirements of the application of a vacuum pump.
    • Generation of geometry features for vacuum pumps with uniform and variable pitch such as volume curve, port areas, leakage areas.
    • Multi-chamber thermodynamic calculation of dry vacuum pumps with or without cooling jacket as well as with water injection in the working chamber.
  • Parametric 3D CAD design and integration with AUTODESK Inventor
    • The full parametric 3D CAD Design and mechanical design of rotors and casings for screw machines. This allows 3D display of rotors in SCORG.
    • 3D CAD of compressor rotors in SCORG and export to variety of CAD formats
    • Full parametric integration with AUTODESK Inventor.

Apart of that, improvements have been made in multi-chamber thermodynamic model:


  • SCORG thermodynamic multi-chamber model has new inputs and equations for calculation of the viscosity of lubricant in the compression process. We introduced MacCoull viscosity model which requires inputs of viscosities at temperature of 40 oC and 100oC.
  • The NIST – REFPROP 10 integration and real fluid definitions are available for both compressors and expanders. SCORG thermodynamic multi-chamber model has an improved convergence and calculation speed for calculation of mixtures of fluids.

Release v2024 also features new templates and extended manuals and tutorials.


SCORG can also be used on Microsoft Azure virtual machines with our SCORG alto cloud platform. Try it here.


To better understand these new features and how they can help you, we will be hosting a webinar series led by our experts Prof. Ahmed Kovacevic and Dr. Sham Rane. Whether you are an existing user or still on the fence about obtaining a license, this webinar series is for you.
