Abstract

This paper examines the discharge of an adiabatic pressure vessel through a converging nozzle. Theoretical analysis is presented based on the assumption of adiabatic flows. The model predicts an exponential pressure decrease during discharge versus time, which agrees with experimental results. There appears to be heat transfer during depressurization or otherwise the gas temperature would fall more than 10K.
