Résumé

In this article, both theoretical and experimental analysis on the performance of a new scroll expander is presented and discussed. Various working chamber volumes from suction to discharge are defined. Thereafter, the evolution and derivative of the working chamber volume with respect to the orbiting angle are discussed. In order to investigate the performance of scroll expander, a detail thermodynamic modeling based on energy and mass balances is established. Radial and flank leakage, heat transfer between the working fluid, scroll wraps and plates are considered in the thermodynamic modeling. Volume, pressure, mass flow of working chamber and power are investigated by solving the thermodynamic modeling. A simple experimental rig for scroll expander is set up. From the comparison of the simulated and measured data, it can be seen that the expander model predicts the output power very well (within 5%). So the proposed mathematical modeling can accurately describe all the suction, expansion and discharge processes for scroll expander.
