SCORG

Industry leading grid generation and performance prediction software for positive displacement screw machines

Design, Analyse and Optimise your screw machines with the industry leading analysis software SCORGTM.

 

DESIGN

Rotor Profile Design

Importation and manipulation of rotor profiles from point coordinate files, scanning of the rotor geometry which can be obtained in SCORG by profile generation or extracted form CAD.

Geometry Analysis

Calculation and graphical representation of the working chamber volume, areas of the inlet, outlet and other ports and leakage areas between the working and neighbouring chambers.

3D Grid Generation

Calculation of the computational numerical grid of moving rotor domain and stationary inlet and outlet domains which are supplied to commercial CFD solvers for analysis.

ANALYSIS

Multi-Chamber Thermodynamics

Geometric analysis of flow features and preliminary performance analysis using multi-domain chamber model. Thermodynamic results can be used as initial conditions or boundary conditions for CFD, Structural Analysis by Finite Element Methods (FEM) or Fluid solid interaction (FSI)

CFD Performance Calculation

Allows accurate CFD performance prediction using commercial CFD codes such as Simerics MP+, ANSYS CFX, ANSYS FORTE, ANSYS FLUENT, STAR-CCM+ and open CFD codes such as OpenFOAM.

OPTIMISATION

System Analysis

A GT-Suite system model can be used for design optimisation using a direct coupling with GT-Suite Thermodynamic Solver

All SCORG parameters can be passed to the optimisation algorithm for analysis

Optimised Rotor, Housing and Port CAD can be exported as STEP, IGES or STL.

CFD Analysis

Rotor and Port geometry can be optimised using the CFD Analysis. Fast CFD Grid generation can be used for improving and virtually testing various parameters of the Rotor design as well as Ports and operating conditions such as in oil injected compressors.

Jon Harrison - Staff Engineer at Gamma Technologies LLC

Here at OMIQ, we are specialised in vertical solutions for the virtual design of flow components. When a customer asked for the possibility of calculating a screw pump, we immediately thought about SCORG. And we were right! The tool is friendly, quick to learn and provides all the relevant design information. It also generates high-quality meshes for our main CFD simulation tool, SimericsMP. Overall, a very productive and fruitful experience.

Federico Monterosso - Sales Director at OMIQ

SCORG software is a valuable tool for anyone designing positive displacement screw compressors. Aside from the capability to generate complex CFD meshes, the lower-order thermodynamic model and related calculation tools provide everything needed for the basic design and performance evaluation of screw compressors. The team at PDM Analysis are very supportive and this is reflected by the new features and improvements introduced in every new release.

Dr David Buckney - Chief Engineer at Mayekawa UK Ltd.

We started using SCORG in 2018 to improve the quality of fluid-dynamic design of screw compressors. Both thermo and mesher modules of SCORG are great and powerful tools to help screw compressor designers and CFD analysts to improve the performances of the product, shortening design time and lowering costs for new product development and verification.

Luigi De Franco - Senior Mechanical Engineer, Head of fluid - dynamic design and CFD calculation office - R&D department at Termomeccanica

Early on Professor Kovacevic helped me learn and use SCORG. It has become and valuable tool that is used at Trane for creating meshes for screw compressor CFD analysis. I have been using SCORG for several years and it has helped Trane to create several different screw compressors designs. I have also presented several times at City University during the short course about how I have used your tool.

Scott M. Branch - Senior Compressor Design Engineer & the SME on screw/scroll compressor CFD analysis at Trane

For approximately one year, I have been using SCORG multi-chamber thermodynamic modelling for design review and optimisation. Various projects have been modelled in this time, including oil-injected and oil-free machines. I can thoroughly recommend SCORG as a design tool. My preferred method of working is to use Scorpath for rotor profile optimisation, tooling, and CAD modelling, then importing the profiles into SCORG for performance evaluation and optimisation of the complete design. After verification, it is easy and cost-effective to apply virtual testing of a proposed design by simply changing the input conditions. I find it hard to imagine a screw compressor design without using SCORG now.

Graham Stupple - Development Engineer at Jäcklin GmbH

SCORG is a very professional software. We mainly use it to generate the grids for screw pumps.

Shuaihui Sun - Associate Professor at Xi’an University of Technology

As a part of our development process, we use SCORG mainly for the discretisation of the fluid domain and obtaining pressure and temperature information which is a challenge because of the moving mesh conditions of screw rotors. Once this information is obtained, a Computational Fluid Dynamics (CFD) and structural analysis is carried out for design validation for customised solutions. SCORG has not only made contributions at the design level but also during the analysis of root cause finding for some of the failures. This was done by simulating actual operating conditions in SCORG and finding out the localised thermally stressed regions within the compression chambers. After we were introduced to SCORG, it has become a standard tool we use in our company to analyse the performance of our screw compressors.

Suraj Abdan - Manager, Design and Development, Air Compressor Division at Kirloskar Pneumatic Company Limited, Pune, India
