Increasing demands for high-performance screw pumps in oil and gas as well as other
applications require deep understanding of the fluid flow field inside the machine. Important …

Screw compressors generate a substantial level of noise during operation. The first stage in
reducing it is to identify and minimize its causes. To this end, sources of noise within these …

Previous publications show that computational fluid dynamics (CFD) can be readily used for
the flow prediction and analysis of screw compressors. Several case studies are presented …

Schraubenkompressoren sind in der Industrie weit verbreitet und dadurch für einen großen
Teil des weltweiten elektrischen Energieumsatzes verantwortlich. Die in der Regel in …

Positive displacement screw machines are classified as compressors, expanders, extruders,
blowers, vacuum pumps, liquid and multiphase pumps. They are commonly used in …

Screw compressors are mature products used broadly in industrial applications. Similar
technology is applied for industrial expanders, pumps, vacuum pumps… Mathematical …

In a screw compressor, both pressure pulsations in the discharge chamber and performance
are affected by the design of the discharge port. A function for calculating the real flow area …

Oil injected screw compressors used for air applications and refrigeration are usually
installed in simple packages which often do not include oil pump for supply of oil to the …

An experimental and analytical study of screw compressor operation under unsteady
conditions has been carried out. For this purpose a one dimensional model of the processes …

Oil injected screw compressors, used for air compression, refrigeration and air conditioning,
