Summary

A mathematical model has been built which includes thermodynamic, mechanical and generator models. Then, the starting procedure of scroll expander driven by compressed air has been simulated. The rotating speed and stable time influenced by the suction pressure, discharge pressure and load resistance have been analyzed. The results show that the starting procedure of scroll expander is determined by the suction and discharge parameters, the load and the geometric parameters of expander. The rotating speed is affected by the driving force of air and the resistance of generator. The rotating speed increases but the increment decrease with the starting time until the expander runs steadily. The stable time and final rotating speed increase with the increase of both suction pressure and electric resistance but decrease with the increase of the discharge pressure.
