Join us for a technical talk by Ted Perry award-winning researcher Nausheen Basha PhD. Nausheen will present her work at a free webinar on 3 February 2022 For full details and to register here.  

The accompanying summary paper outlines her research into the performance and reliability of oil-injected screw compressors. It explains how the oil injected in a twin-screw compressor distributes itself in the compression chambers and how CFD (computational fluid dynamics) were used as part of this research. Case studies, tests on existing rigs and instrumental detail show the effect of using different injection points and how to reduce power losses due to temperature rise.
