Water Flooded Single Screw (SSP) Compressor Technology

Economics of water injected air screw compressor systems

There is a growing need for compressed air free of entrained oil to be used in industry. In many cases it can be supplied by oil flooded screw compressors with multi stage filtration systems, or by oil free screw compressors. However, if water injected screw compressors can be made to operate reliably, they could be more efficient and therefore cheaper to operate. Unfortunately, to date, such m...

Design and Development of A Water-Flooded Screw Compressor Packaged Air Supply System

Computer Modelinq of an Oil Flooded Single Screw Air Compressor

A computer model of a single screw oil-flooded low pressure air compressor was developed which predicts the internal conditions based on certain empirical values. A characteristic thread technique is used for steady state operation. A polytropic process is used and the model will iterate for the polytropic coefficient to best correlate internal predictions with empirical values. The geometric v...

CFD Analysis of Oil Flooded Twin Screw Compressors

Modelling of screw compressors using Computational Fluid Dynamics (CFD) offers better insight into the working chamber of twin screw machines when compared with chamber models. As shown by authors in earlier publications, CFD models predict performance of dry gas and refrigeration compressors fairly accurately. However numerical flow models used for modelling of oil flooded twin screw compresso...

The Design of a Family of Screw Compressors for Oil–Flooded Operation

The design of a family of efficient oil-flooded twin screw air compressors was performed at City University London for Elgi Equipments Coimbatore, India. It was carried out using a software package, which included almost every aspect of the rotor profiling and compressor thermodynamic and geometric modelling with the capacity to transmit calculated output directly into a CAD drawing system.
