Dynamic modeling of a poppet valve for use in a rotating spool compressor.

The operational efficiency of the rotating spool compressor, first introduced by Kemp et al. (2008), has been improved in recent years through the modeling of various elements in the compression cycle. In order to continue the advancements of the design, a model for predicting the discharge valve dynamics is introduced. The model is created using high-pressure measurements both upstream and downstream of the valve. The model is able to predict the initial valve displacement with a mean absolute percent error of 6.91%. The model is also able to predict the amount of time the valve is open in one valve oscillation with a mean absolute error of 9.51%.
