Knowledge Base Repository
In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters.

Abstract:
Close control of the clearances between the rotors and the casing is essential for efficient and quiet oil free compression or expansion in twin screw machines. Differential thermal expansion between these components can therefore have adverse effects, especially when both functions are performed by the use of only one pair of rotors in a single casing. A plain compressor and a combined compressor-expander are analysed and it is shown how good results can be obtained by the use of different materials for each component. The analytical results show good agreement with experimentally derived data.
