Notice of Retraction Numerical simulation of a scroll compressor used for Compressed Air Energy Storage

The paper presents a thermodynamic model for a scroll compressor used for Compressed Air Energy Storage. The model includes energy conservation equation, instantaneous volume equation and gas leakage equation. The numerical simulation results are achieved by means of the 4th order Runge-Kutta method under Matlab and are compared with the experimental values. Different performance parameters of the scroll compressor including the delivery, pneumatic power and energy conversion efficiency are analyzed. The comparison between the simulation and the experiment indicates that all the parameters show the same changing trend with some deviation, which may be caused by some ignored factors in the thermodynamic model like the heat loss, the throttling loss and the mechanical friction loss. Finally the paper provides the suitable running conditions for the experimental prototype.
