Modeling Compressible Air Flow In A Charging Or Discharging Vessel And Assessment Of Polytropic Exponent

Abstract

In this work, the classic problem of charging and discharging of a pressurized tank is studied. This experiment allows students to gain a deeper understanding of polytropic processes and compressible flows. The experiment apparatus described in this study allows for direct measurement of the pressure and temperature within the tank, and utilizes a LabView based computerized data acquisition system. To assure accurate measurements of these parameters, a fast-response thermocouple and a high accuracy variable reluctance pressure transducer is employed.
