Unique Design and Evaluation Solution for Positive Displacement Screw Machines

Posted By: Simerics, Inc
Date:Thu, 11 Sep 2014, 11:16 p.m.

PDM Analysis Ltd ( and Simerics ( ) have teamed up to offer the unique solution for design and development of positive displacement (PD) screw compressors, pumps and motors through an integrated design and analysis tool set consisting of SCORG™ and PumpLinx®. This software suite characterized by fast model set-up, high accuracy and fast computational speed will help companies create an optimized and innovative design of screw machines for improved performance and reduced cost.

Building on the latest simulation technologies, SCORG™ and PumpLinx® offer the designer an integrated virtual tool to drive the design, development and optimization of positive displacement screw machines capable of simulating the full range of operating conditions, including clearance management, real gas multiphase flows and cavitation. The user friendliness and robustness of this tool will allow companies to design superior screw machines with reduced design efforts, fewer hardware tests and shorter product development cycle times.

About PDM Analysis Ltd:

PDM Analysis Ltd ( is the UK based company which offers advanced software, services and consultancy for positive displacement screw machines. The expertise and experience of our staff in the field of screw compressors was built over last 25 years through collaboration with leading industrial and academic customers and partners worldwide. We are closely associated with City University London where SCORG™ was originally developed.

SCORG™ is the unique software tool for design, grid generation and pre-processing for CFD of positive displacement screw machines. It is designed to minimize efforts and maximise efficiency of the design process by enabling evaluation and manipulation of rotor profiles, geometry, preliminary thermodynamic analysis and grid generation of the large number of positive displacement rotary machines with variety of rotor combinations.

About Simerics:

Simerics, Inc. ( ) is the US based company which offers unique and innovative computational fluid dynamics (CFD) software to drive the design and development of many products, one of which is screw machines. We have offices and distributors world-wide and our staff have decades of experience over broad areas of CFD. Many of the biggest companies in the world have become our partners and customers.

PumpLinx®is the CFD software from Simerics that is particularly strong in several categories of applications, one of which is positive displacement screw machines. Other strengths of this software include a wide range of components such as valves, bearings, fuel injectors, gear box, heat exchangers and complete 3D CFD models of fluid systems. PumpLinx® is the only software available that can simulate many of the pump, compressor and valve designs; for many others, it is the only one that can generate accurate solutions within reasonable turn-around times. Key advantages of the software include accuracy, faster computational speeds and significantly lower model set-up times.
