Scroll Expander; Mathematical modeling; Experiment; performance
In this article, both theoretical and experimental analysis on the performance of a new scroll expander will be presented and discussed. In order to investigate the performance of scroll expander, a detail mathematical modeling based on energy and mass balances is established. Radial and flank leakage, heat transfer between the working fluid, scroll wraps and plates, friction losses are considered in the mathematical modeling. Volume, temperature, pressure, mass flow of working chamber, friction loss power of moving parts, efficiency and power are investigated by solving the mathematical modeling. The experimental rig for scroll expander is set up. Results for various operational conditions are shown and discussed.
