Abstract

In this paper, a thermodynamic model for the analysis of screw expander performance is presented. The model estimates the work output of the expander by considering the work availability of the expanding fluid in a typical cycle. The validity of the proposed model is checked by using some of the experimental data that are available in the literature. Further parametric studies are also conducted to improve the understanding of the blowdown and blowback effects, the blowdown mass and pressure ratio, and the overall isentropic efficiency of the expander. The types of working fluid used by the expanders are dry saturated steam and high quality steam.
