Validation of performance for a novel compressor-expander concept.

Number: 1350

Author(s) : PEARSON A., FENTON J., SUBERT J., CARMICHAEL C.

Summary

A novel mechanism that can be adapted for use as a compressor or as an expander is described. The results of detailed modelling of performance in both modes are presented in the form of graphs of isentropic and volumetric efficiency plotted against pressure ratio and pressure difference. These are compared and contrasted with equivalent graphs for conventional types of compressor. This comparison is used to demonstrate how the novel concept combines the benefits of both reciprocating and screw compressors and expanders. The model results are validated against performance data measured on a test cell designed to enable rapid testing across a range of operating conditions and the comparison is used to fine tune the model, enabling other configurations of compressor and expander to be simulated. A detailed description of the test cell is provided and proposals for future development of this work are suggested, with some possible new applications for the novel concept.
This paper is part of a series of presentations and extends work presented at previous conferences, including the Herrick Compressor Conference in 2022. This paper includes performance data that has not previously been published and the discussion explores some explanations for the differences between the novel concept and conventional compressors.
